Method Detail

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Usage:
java skyview.util.CoordsPixel file lon lat
where file is the name of the FITS file and lon and lat are the celestial coordinates (in the coordinate system of the image for which the pixel 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
