Release Notes Version 4.2
Part of HEAsoft 5.3 - November 17, 2003
Changes in version 4.2
- WCS support added using Starlink AST library. Ximage now
recognizes the coordinate systems defined in the WCS
convention, enabling grid plots and coordinate conversions in such
systems.
- Swift XRT support
- Ability to read in event file with a rebin that is a real value. For example, rebin=0.5 in the case of Chandra subdivides the standard pixel size in half.

- curve - Draw path of shortest distance between to sky positions
- moper - Perform elementary math operations between maps
- remap - Remap image to new coordinate system, resampling pixels by a variety of methods
- wcs - Manage internal wcs data structures

- equinox - Set the equinox of the plotted coordinates
- labcolor - Set color of numeric labels
- nolabel - Omit numeric labels
- map
- isequal - Return whether mapids correspond to same map
