NOTES

1. The following header information is printed:

    
              7  FMAX  = IMAGE MAXIMUM 
              8  FMIN  = IMAGE MINIMUM 
              9  AV    = IMAGE AVERAGE 
             10  SIG   = STANDARD DEVIATION (SQ. ROOT OF VARIANCE) 
             15  PHI   = EULER ANGLES: ANGLE AROUND Z 
             16  THETA = EULER ANGLES: ANGLE AROUND Y 
             17  PSI   = EULER ANGLES: ANGLE AROUND Z  
             18  XOFF  = X OFFSET 
             19  YOFF  = Y OFFSET 
             20  ZOFF  = Z OFFSET 
   

2. Angles: PHI, THETA and PSI (often also referred to as GAMMA) have meaning consistent with the operation where they are set (see commands 'RT', 'PJ', 'BP' etc.).
