Primary Array

This is a sample FITS header for an image stored in a FITS primary array.

SIMPLE  =                    T / file does conform to FITS standard
BITPIX  =                   32 / number of bits per data pixel
NAXIS   =                    2 / number of data axes
NAXIS1  =                  300 / length of data axis   1
NAXIS2  =                  200 / length of data axis   2

CRPIX1  =                  150 / reference pixel
CRVAL1  =                45.83 / RA at the reference pixel
CDELT1  =           -.00277777 / increment per pixel (degrees)
CUNIT1  = 'deg     '           / physical units of axis 1

CDELT2  =            .00277777 / increment per pixel (degrees)
CUNIT2  = 'deg     '           / physical units of axis 2
CROTA2  =                 30.0 / image rotation (degrees)
