check that the FT1 files haven't changed

Maria-Elena reprocessed a couple of runs:

  • Philippe: I've compared the new FT1 file with the original file root://glast-rdr.slac.stanford.edu//glast/Data/Flight/Level1/LPA/prod/5.7/ft1/gll_ph_p305_r0634008661_v000.fit and the key variables (energy, direction, event class and types) are identical. The nb of events in the files are also identical.
  • Don:

    I compared the original and new photon and event files that Maria Elena created. The data in the photon (FT1) files match exactly. The event files (LS1) have small differences in the PtAlt, PtLat, and PtMagLat columns. Looking at a few examples, the differences are in the fourth significant figure or lower (e.g., 537.501 vs 537.494 in PtAlt). I assume this is because of the change to the geodetic position calculation implemented for the FT2 files. I compared PtAlt values in the LS1 file against RAD_GEO values in the FT2 file for the reprocessed run and they are consistent, so that checks out. I supposed if we were to do everything properly we would need to reprocess all the event files, too, but I think we can just document the issue and move forward since the differences are small.
