        java skyview.util.CoordsPixel file lon lat
        where file is the name of the FITS file and lon and lat are the celestial J2000 coordinates Note that the pixel coordinates for an NxM image run from 0 to N and 0 to M. The standard definition used within FITS for coordinates (e.g., in the CRPIX values) would range from 1/2 to N+1/2 and 1/2 to M+1/2.
