HEAsoft v5.2 Released


We are pleased to announce the release of HEAsoft v5.2


1. How to obtain HEAsoft v5.2


HEAsoft v5.2 has been released, and can be obtained from:

http://heasarc.gsfc.nasa.gov/docs/software/lheasoft/

This is where the most up to date HEAsoft information is available, including notices of the releases, HTML documentation, and the continually updated FAQ. Users should always check here first for answers to questions.

Any problems installing FTOOLS should be reported via the Feedback form (select "FTOOLS" from the menu). There is also a XANADU option for Questions on the installation and usage of XANADU software package.

2. New/updated tools related to ASCA data analysis


Updated in HEAsoft v5.2

Uninitialized variable problems in ascalin and others
We have identified and fixed many "uninitialized variable" problems which manifested itself only on Linux machines (in particular, the HEAsoft v5.1 version of ascalin on Linux often hang or incorrectly claimed that event times were out of range of the gain history file). We have also discovered and fixed uninitialized variables in faint, sispi, mkgisbgd, and mkdtime, although these rarely affected the results.

ascaeffmap
Fixed a bug in calculation of the SIS efficiency from the RMF.

ascaray
Changed default "goldens" parameter to 18.5 g/cc, reflecting our current calibration (previously, the default value was 19.3, the bulk density). The use of the higher density value would have resulted in an overestimate of the high energy effective area.

fmosaic
Fixed a bug so it will run on Solaris.

Further information on changes can be found in the general HEAsoft 5.2 release notes.
