SAOImage DS9 Version 4.0 New Features
Backward Compatibility Issues
A number of minor changes have been made to DS9 and the XPA and Command
line
interface of DS9 to bring about a more consistent behavior. While all
efforts have been made to provide backward compatibility, in a few
cases, this was not possible. Below is a list of changes in which
backward compatibility was not
maintained:
- xpaset -p region <filename>
The defaut argument
is now assumed to be a file name of a regions file, not a text string
defining a region.
Catalogs
DS9 provides full support for loading, displaying, filtering, and
saving catalogs. Most major catalogs can be retrieved from online
servers.
2MASS Image Server
In addition to the DSS image server, DS9 now provides support for the
2MASS image server hosted by IPAC.
Composite Regions
A Composite Region is a region which is a collection of other regions,
which share common properties. A composite region is composed of a
center point and a rotation angle, of which all its members are
rendered in reference to. For more information see Composite Region
Template Regions
A Template Region is a special form of a region which is saved
in
a special wcs coordinate system WCS0. WCS0 indicates that the ra and
dec values are
relative to the current WCS location, not absolute. For more
information see Template
Region
Instrument FOV
DS9 now supports a number of instrument field of view region templates.
To select an instrument fov region, select 'Regions:Shape:Instrument
FOV'.
New Regions
DS9 now supports ellipse panda (epanda) and box panda (box panda)
funtool regions.
Smoothing
Support for smoothing has been expanded to include support for images,
binary tables, data cubes, and mosaics.
