FITS file - 1st extension

The 1st extension holds a 1x1 arcmin thumbnail image of a SuperCOSMOS scan of the UKST Bj (IIIaJ) survey plate.

Example header:

SIMPLE  =                    T / file does conform to FITS standard             
BITPIX  =                   16 / number of bits per data pixel                  
NAXIS   =                    2 / number of data axes                            
NAXIS1  =                   89 / length of data axis 1                          
NAXIS2  =                   89 / length of data axis 2
