Improvements, Modifications, Corrections

19 July 2010: V3.4.4.0
- Mission file (.cen): the type of Creme96 solar flare model chosen by the
user was not saved in the mission file. This has now been fixed. Three new
lines have been added in the *.cen file that indicate if “worst 5 min”,
“worst day” or “worst week” was chosen.
- External flux import module: a bug in the atomic displacement calculation
has now been fixed.
- Thickness table definition module (Dose, Atom. Displ.): when the user chose
to change the default thickness values, changes for fields 61 to 70 were not
taken into account. This has now been fixed.
- LET module: a bug in the calculation of the mission average LET for cosmic rays
when the magnetospheric shielding was considered has been fixed. The bug only
affected elliptic orbits.

7 May 2010: V3.4.3.3
- Solar Particle module/Creme 96 model: a bug in the progress bar definition
(bar that appears during calculation) caused OMERE to crash. This has now
been fixed.

29 April 2010: V3.4.3.2
- Solar Particle module: when Creme96 was used and the magnetospheric cut-off
was not selected, integral fluxes were not calculated. This has now been fixed.

14 Avril 2010: V3.4.3.1
- Dose, Displacement Damage and Solar Cell calculations using the environment
flux “from mission data” when IGE2006 or MEOV2 models were chosen gave a null
result. This has now been fixed.

13 Avril 2010: V3.4.3.0
- IMPORTANT CORRECTION in the Solar Particle and Cosmic Ray modules: in the
case the Creme96 model was used to calculate heavy ion fluxes, the
magnetospheric cutoff was not correctly applied. This affects only lower than
geosynchronous altitude orbits.

30 March 2010: V3.4.2.1
- Cosmic Ray/Creme96 module: a bug has been fixed that didn’t allow SEE
multi-component calculations using the mission’s environment (with Creme96
chosen in the Cosmic Ray module) to be performed.

26 March 2010: V3.4.2.0
- Multimission module: batch calculations can now be performed for solar
flare heavy ions using the Creme96 model.
- Multimission Post-Processing: post-processing can now be performed for
interplanetary proton batch calculations.
- SEE module: the axis for the proton cross section graph in the case PROFIT
or SIMPA are used are now adjusted for each component so that the data can be
clearly seen on the graph.
- Write and Read Mission File: the atomic number of elements chosen for the
Creme96 model were not saved in the mission file. This has now been corrected.
- Read Mission File: some mission files created with V3.3 or previous versions
could not be well read by the new V3.4 OMERE version. This has now been corrected.

21 January 2010: V3.4.1.0
- IMPORTANT CORRECTION in the Solar Particle module: in the case the Creme96
model was used to calculate differential and integral fluxes, the magnetospheric
cutoff was applied only to differential fluxes.
- SEE module: the user is now allowed to enter the number of sensitive cells
using a scientific notation, like for example 1E5. However, the size of this
number cannot be higher than the size of an integer (~2e9).

4 January 2010: V3.4.0.0 new major release!
The major improvements are:
- MEO v2 solar cycle dependent trapped electron model.
- Worst date calculation for IGE 2006 trapped electron model.
- CREME 96 fluxes for solar and cosmic ray ions.
- Use of a personalised energy grid for trapped particle and solar proton fluxes.
- Solar flare worst 5 minute proton fluxes.
- Definition of a new material with NEMO.
- Cartography minimum and maximum values.
- Input files can include numbers expressed with a “,” instead of a “.”

See the updated user manuals for more details.

----------------------------------------------------------------------------

23 November 2009: V3.3.3.0
- IMPORTANT CORRECTION in the LET and SEE environment modules: in the case the user
chose to use input proton flux files and the energy and flux included in those files
where not in MeV and MeV-1.cm-2.s-1 or cm-2.s-1, respectively, then the unit
transformation was not done correctly. This error has now been corrected.
- Solar Cell module: in the case the English version of OMERE was used, the calculation
could not be performed. This bug has been corrected and the solar cell calculation is
equally accessed from the French and English executables.
- SEE data base module: in the case the user defined the cross section data of a
component in the data base from a file, the values included in the file are saved in
the data base and when the component is chosen these values appear in the corresponding
field in the cross section data dialog window.
- SEE module: the visualisation of the LET-cross section curve has been modified. The
y axis is now adjusted based on the minimum and maximum data values.
- SEE module: a modification has been done so that if the user changes the number of
sensitive cells the cross section visualisation button for ions only becomes invalid,
alerting the user that the cross section calculation has to repeated. In the same way,
if the user changes the cell depth, the cross section visualisation button for ions
(and protons when the Simpa and Profit methods are used) becomes invalid, alerting
the user that the cross section calculation has to repeated.
- Multi-mission execution module: a bug in the SEE multimission calculation has been
corrected. Calculations are correctly done and written in the case that the Simpa or
Profit methods are selected for protons.
- Multi-mission post-processing module: a bug in the SEE multimission post-processing
calculation has been corrected. Error rates were not written correctly in the output file.
- Transport module: the output file in excel format is now written correctly.
- Solar Particle ESP module: the output file in excel format is now written correctly.

19 October 2009: V3.3.2.3
- Atomic Displacement: the choice of NIEL electrons or protons in the window that
appears when the user presses the button “Options”, for a periodic calculation + graph,
has been cancelled. OMERE performs the calculation (and plots equivalent fluences on
the orbit) based on the choices made in the Parameters window.
- Multi-mission Post Processing: a bug in the atomic displacement calculations is fixed.
The files are now correctly read and written.

25 August 2009: V3.3.2.2
- SEE module: a modification has been made so that if the user changes the number of
sensitive cells the cross section visualisation button for ions and protons becomes
invalid, alerting the user that the cross section calculation has to repeated.
- SEE module: a modification has been made so that if the user modifies the ion cross
section input- and at the same time has chosen to do the proton calculation with SIMPA
or PROFIT- the cross section visualisation button for protons becomes invalid,
alerting the user that the calculation has to repeated.

21 July 2009: V3.3.2.1
- SEE module: a modification has been made so that if the user chooses to use the
Weibull fit parameters and then closes the dialog box, the choice is saved by OMERE.
- SEE module: : a modification has been made so that the name of input files for the
environment are shown in the main window only if the user has chosen this option.

8 July 2009: V3.3.2.0
- IMPORTANT CORRECTION in the SEE Environment module: bug concerning the value of the
shielding thickness, in the case when the environment is defined by the models selected
in the current mission, has been fixed. OMERE considered thickness values in g/cm2
independently of the units chosen by the user.
- SEE module: when fitting the cross section data for ions and protons, if the user
changes one or more of the calculation parameters: LET threshold, limit cross section,
W or S, then if he needs to go back to check the data by pressing for example the
“Heavy ion cross section data” for the ions, the new parameter values are not lost.
Just remember to press “cancel” and not “done” when on the cross section data dialog
box!
- Multi-Mission Post Processing module for LET spectrum: bug concerning the choice of
differential or integral flux has been fixed. When the user asked for differential
fluxes OMERE recovered integral ones and vice versa.
- Multi-Mission Post Processing module for Solar Cells: dialog box and output file
have been changed to fit the user’s needs. Now one can choose the output type (which
kind of equivalent fluence) and the units for the shielding thickness values to be
included in the output file. The latter has two columns: one for the thickness values
and one for the equivalent fluences.
- Multi-Mission execution module: now the user can use files as input to the various
modules of each mission and run the batch mode. The only module for which this is not
valid is the LET spectrum module.
- Mission module: eccentricity can now take the value of zero.
- Values of semi-major axis and eccentricity are now written in the mission file (in
the case that they are defined by the user) and can be changed by hand directly at the
.cen text file.

10 June 2009: V3.3.1.0
- SEE module: it is now possible to insert in the data base a component for which only
ion calculations are performed.
- SEE module: the bug concerning the insertion or modification of a component- for
which calculations have been performed with PROFIT or SIMPA- in the data base has been
fixed.
- SEE module: a bug has been fixed, it concerns the proper visualisation of the
LET-cross section curve in the case that it is determined by the Weibull fit parameters.

29 April 2009: V3.3.0.2
- SEE module: the bug allowing to choose two options at the same time in the ion cross
section window has been fixed.
- SEE module: the values of proton cross sections estimated via the SIMPA method are
now written in the output file.

24 March 2009: V3.3.0.1
- A new batch multimission module is available in OMERE. This module permits to launch
a multiple mission calculation. It can be found in the “Options” menu.

12 March 2009: V3.3.0.0 new major release!
The major improvements are:
- Cosmic Ray fluxes can now be plotted in the OMERE interface.
- Interplanetary solar proton and ion fluxes can be calculated by applying a weighting
factor which depends on the distance from the Sun.
- All OMERE output files can now be created in EXCEL format.
- An expert/standard module has been created.

See the user manual for more details.

----------------------------------------------------------------------------

22nd August 2008 : V3.2.1.0
- LET : A bug has been fixed for the calculation of the LET spectrum for GTO mission
considering the magnetospheric cutoff. Only the LET spectrum was wrong, the energy
spectrum of cosmic rays calculated on the cosmic ray window was OK.

8th March 2008 : V3.2.0.1
- NIEL (NEMO): The NIEL run was stopped and the soft crashed when elements with no
inelastic data was selected (Mercury Hg) for example. The run is now possible with only
the elastic data. A warning is displayed concerning the domain of validity of such NIEL
values.

30th January 2008 : V3.2.0.0 new major release
The major improvements are :
- Use of SRIM2006 data for LET and transport module. A switch button between CREME and
SRIM data is available in the new [Options : Parameters] menu.
- new [SEE : Effective LET] menu. It allows to estimate the effective LET of an
incident particle in a chosen sensitive region in the component die.
- The environment LET spectrum can now be calculated from proton and ions flux files
and not only from OMERE environment module parameters.
- SEE rate can be calculated directly for the current mission.
- The user can set up its own mission data base in the mission list box of the [Mission
: Parameters] dialog box.

Be careful that now OMERE opens by default a geostationnary orbit at 160°W (worst case
position).

---------------------------------------------------------------------------------------------

6th November 2007 : V3.1.3.0
- NIEL (NEMO) minor changes of NIEL values calculated by NEMO for compound materials.
- SIMPA (SEE) : the proton cross section button was not automatically validated when
SIMPA option is chosen. This has been corrected now.
- SHIELDOSE : numerical noise appeared in the calculated doses when the solar proton
flux is null (solar active period=0). Now the corresponding dose = 0.
- a temporary file was created and not deleted when the mapping function is used. It is
deleted now at the end of the calculation process.

29th may 2007 : V3.1.2.0
- JPL91 : Some calculations errors occurred when the active period is 4 or 6 years. It
calculation routine has been modified and completely re-validated.

18th April 2007 : V3.1.1.7
- minor bug in the title of the "save as" window.
- The creation of the bmp file corresponding to the cross section curve was sometimes
disabled. It is OK now.
- the M index (CREME index) was written in the result file even if GCR ISO is used. Corrected.

12th january 2007 : V3.1.1.5
- Bug fixed in the calculation of solar active period for a launch date after 2009 and
a lifetime greater than 15 years.
- The choice of "JPL1 extended" option is now saved in the mission file (menu File:
Save).
- NEMO : the atomic mass of Germanium (Ge) is now 73 (previous value 74) in order to
deal with the NEMO data base.
- JPL91 : Smoother spectrum is calculated for proton flux with a JPL91 confidence level
higher than 95%.

5th December 2006 : V3.1.1.3
- ESP is now linked to the DOSE, DDEF and solar cell module

8th November 2006 : V3.1.1.2
- Modification of the AE8 AP8 modules to avoid wrong values when the L (Mc ilwain)
parameter is too high.
- bug fixed in the Dose module when only "other electrons" flux file is used for the
calculation.
