      • Need to disallow CSSISpaceWeatherFile for PredictedWeatherSource and remove as an option from GUI (let GUI tester know).
        Done
      • * Propagation using CSSI file has a numerical issue. See below

      If i comment out the CCSI config (lines 29 and 30) and use constant data, I get the following from GMAT, STK and MATLAB for the last row of data in the report.

               -5114.08882165686
               -281.017485482097
                  4376.730927939
      

      If I include lines that turn on the CSSI file then GMAT is off by several hundred meters
      Truth Data from MATLAB Propagator USING the CSSI file

      MATLAB  -5110.58306598338    -271.65381968422     4381.84485111088
      STK     -5110.584168146387   -271.65670971167197  4381.84329571158470
      GMAT    -5110.522505999485   -271.4945980152261   4381.930892193545 
      

      MATLAB and STK agree to a few meters, but GMAT is off by about 200 meters.

      I believe this is partially due to the fact that when using daily values for Ap, you need to change one of the input flags to the MSISE models. The call sequence looks like this

      [T, RHO] = atmosnrlmsise00(H, LAT, LON, YEAR, DOY, SEC, LST, F107A,
          F107, APH, FLAGS, ITYPE, OTYPE, ACTION)
      

      where FLAGS is a vector. In MATLAB (which indexes from 1), you set Flag(9) = -1 when using the daily values off of the CSSI file. (C interface may need element 8, not sure)

            Now at ~4 m difference from STK for the test case.

            Reopened to look at the JR and other MSISE model test cases

            I think these are resolved by truth data corrections. Passing to Steve to confirm by closing.

            MISIS is done.

            I think there may be an issue with JR communicated via email. We need to take a last look at what were are doing and make sure we think it is correct, then document if so.

            JR was the only test still failing. Test is now passes in my local build. I'm going to close. If there is an issue, the test system will let us know and we will re-open at that time.
