If you want to find where-abouts in an image a particular point on the sky is
positioned, or conversely what celestial coordinates correspond to a given
position in the image, SKYPOS can be used. SKYPOS can also
give information about the local pixel dimensions and image orientation at any
position within an image. These can vary across large images because of
projection effects.
