The following file are needed 1) RPCMAG_SC_ALIGN.TXT 2) RPCMAG_GND_CALIB_FSDPU_FMIB.TXT 3) RPCMAG_GND_CALIB_FSDPU_FMOB.TXT 4) RPCMAG_002_CALIB_IB.TXT 5) RPCMAG_002_CALIB_OB.TXT The first file contains the rotation matrices to turn the magnetic field vector from instrument coordinates to s/c-coordinates. There are two matrices for each sensor: one for the stowed boom and one for the deployed boom position. The two GND files contain all information to calculate the temperature dependent sensitivity, misalignment and offset of the IB and OB sensors (FM units) connected to the Flight-spare (FS) DPU. This correction is based on Ground Calibration Results. For an improvement of the calibration the two Inflight Calibration File for Temperature Model 002 are used. These two files contain the actual Temperature correction polynomial for the sensor offsets. All files are read by the IDL s/w gen_cal_data.pro The GND calibration algorithm is described in the Calibration Analysis report RO-IGM-TR-0003 (Chapters 7 -9), which can be found in the document directory. The Inflight calibration is described in the EAICD. The complete calibration is described in the document RO-IGEP-TR0028 : Step by Step calibration procedure
