Version 0.4.3 of the S-Lang XPA and DS9 module is now available at
http://space.mit.edu/cxc/software/slang/modules/xpa/
The driver for this release was to address two serious issues:
- When DS9 bins images from event lists the FITS header it returns
for the image does not reflect BITPIX=-32, but rather BITPIX=8
from the original event list. This could cause image pixel arrays
retrieved by ds9_get_array() to have the wrong S-Lang datatype
(making them essentially corrupt/unusable); we now check if DS9
has binned the image itself, and if so reset BITPIX accordingly.
- MAC OS/X testing revealed that char arrays returned by the S-Lang
XPAGet() wrapper were not always properly NULL-terminated.
The regression tests were updated to interoperate with a wider number
of DS9 versions, and several minor new functions were added. Please
see the CHANGELOG for more details.
Best,
-- Mike Noble
