                 throws java.lang.Exception

Usage:
java skyview.util.PixelCoords file x y
where file is the name of the FITS file and x and y are the pixel coordinates for which the celestial coordiantes are desired. 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.

Throws:

java.lang.Exception
