Translates a FITS image in X and y, correcting the WCS accordingly

	#!/bin/env python

	# Moves a simple 2D FITS image in X and Y. The output image is the same size as
	# the input image.

	# Usage:
	# move_wcs.py <infile> <outfile> <xshift> <yshift>

Script to rotate the WCS associated with a FITS file using pyast

	#!/bin/env python

	# Rotates a simple 2D FITS image. If <xcen> and <ycen> are specified,
	# the output image is the same size as the input image. Otherwise,
	# the output image is the smallest that will hold all the rotated input
	# data.

	# Usage:
	# rotate_wcs.py <infile> <outfile> <rotation> [<xcen> <ycen>]
