Package astLib :: Module astPlots

Module astPlots

module for producing astronomical plots

http://astlib.sourceforge.net

This module provides the matplotlib powered ImagePlot class, which is designed to be flexible. ImagePlots can have RA, Dec. coordinate axes, contour overlays, and have objects marked in them, using WCS coordinates. RGB plots are supported too.
