MacOSX
MacOSX (darwin) requires the use of X11 for MacOSX 10.2 or XDarwin for MacOSX 10.1. Please refer to the README file. For more information on using DS9 with IRAF under MacOSX, please see The Macintosh IRAF Web Page
Save As Image
There have been several reports of the failure of the Save As Image function. DS9 uses Ghostscript to rasterize the image and graphic data and to convert to one of the supported image formats. However, there seems to be problems with using older versions of ghostscript. In particular, it appears that Ghostscript version 6.50 or greater is required. Below is a list of the versions of Ghostscript that have been tested with DS9:
Port Ghostscript Version Solaris AFPL Ghostscript 7.04 Linux GNU Ghostscript 6.51 MacOSX AFPL Ghostscript 6.50 (2000-12-02) Windows (Cygwin) GNU Ghostscript 6.51 Plot
There is a know bug with Plots and the Zoom function. Bring up an analysis plot. Click left button to start the zoom function. Without completing zoom (by clicking a button), go to FileClose. Resulting error message will appear: An internal error has been detected: invalid command line:".atmenu122g" menu and choose.
In certain cases when the data contains x errorbars, and there values are quite large, compared to the data itself, and if displayed with errorbar style 2, the rendering may become corrupted. In this case, only use style 1.
