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.
