The CALIB directory contains all necessary information to generate            
calibrated magnetic field values from the Inboard (IB) and the                
Outboard (OB) sensor.                                                         
The following file are needed                                                 
1) RPCMAG_SC_ALIGN.TXT

4) RPCMAG_GND_CALIB_FSDPU_FMOB.TXT                                            
5) RPCMAG_yymmdd_006_CALIB_IB.TXT                                             
6) RPCMAG_yymmdd_006_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 second file is used to correct the sensor     
orientation using the analysis result from the first Earth Flyby. By          
comparison with the POMME Earth magnetic field model it turned out, that the  
sensors have to be rotated by some hundreths  of a degree to get the best     
accordance with the model.                                                    
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 006 are used. These two files (calculated          
on daily bases) contain the actual Temperature correction polymomial          
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 :
