Notes:                                                                        
                                                                              
  As of 2014-10-31, all in-flight observations have METs greater than         
  0005257679, the MET of the earliest calibration directory, so the default/  
  and initial/ directory calibration files are never used.                    
                                                                              
  As of 2014-10-31, the errormap calibration files contain all zeroes in their
  first band, and the other band are not used in the calibration.  So all     
  pixels in the error map extension are zero.                                 
                                                                              
  As of 2014-10-31, there are no rollover maps, and the default rollover      
  scheme is used (subtract 4096 from raw values greater than 3850).           
                                                                              
  As of 2014-10-31, all calibration file maps, except for the electronics     
  induced readout signal map elecmap.fit, are copied into one of the          
  extensions of the calibrated data output file.                              
                                                                              
  The per-pixel calibration formula is                                        
                                                                              
    C  = (((S - E ) / F ) - O ) * G  / (I * W  * aOmega * gCorr)              
     i       i    i     i     i     i        i                                
                                                                              
  Where                                                                       
        i is the pixel index subscript, indicating the operation is per-pixel 
          - that is, all quantities with a subscript i in the formula above   
            refer to a pixel (LINE,LINE_SAMPLE) from one of the following:    
            - the raw image input pixel (S), all bands                        
            - the corresponding calibrated image output pixel (O), all bands  
            - the corresponding pixel from one of the calibration file maps   
          - All image, and all map dimensions are [256,256] or [256,256,N]    
            where N refers to the number of image bands (PDS) or planes (FITS)
          - PDS bands are numbered from one to N                              
          - FITS image planes are numbered from zero to (N-1)                 
          - PDS band 1 is the same as FITS plane 0                            
          - PDS band N is the same as FITS plane (N-1)                        
        C is the calibrated output pixel value, erg/s/cm^2/Angstrom/sr        
        S is the raw input pixel value, after correcting for rollover         
        E is the electronics induced readout signal map pixel value, elecmap  
        F is the flat field map pixel value, flatmap.fit                      
        O is the offset map pixel value, calmap.fit, second band              
        G is the gain map pixel value, calmap.fit, first band                 
        gCorr = 0.25, gain correction factor                                  
        I is the intergration time, seconds                                   
        W is the wavelength width map pixel value, wavemap.fit, second band   
        aOmega = 0.004*0.004*PI/((2*8.6)*(2*8.6)), pixel solid angle
