Celestial Coordinates from Image Coordinates

There are several alternative methods for obtaining coordinates from a displayed image. If celestial coordinates are required, the simplest method is to use tvlabel.

*tvlabel, xexamine* -- sky coordinates from a displayed image
*skypix* -- conversion of pixel position to sky coordinates
*wcscoord* -- all purpose coordinate conversion
