        pHeader[ 1 ]: BITPIX  =  16 / number of bits per data pixel
        pHeader[ 2 ]: NAXIS   =  2 / number of data axes
        pHeader[ 3 ]: NAXIS1  =  600 / length of data axis 1
        pHeader[ 4 ]: NAXIS2  =  512 / length of data axis 2
        pHeader[ 5 ]: EXTEND  =  T / FITS dataset may contain extensions
        pHeader[ 6 ]: COMMENT    FITS (Flexible Image Transport System)
        pHeader[ 7 ]: BZERO   =  32768 / offset data range to that of unsigned short
        pHeader[ 8 ]: BSCALE  =  1 / default scaling factor
