Frequently Asked Questions

List of currently outstanding issues.


Patches:

latest update 12.8.2b Jul 31, 2014

Requires patch installer v4.6

To apply patches, you'll need to have downloaded and already built the source code distribution of XSPEC. For details about the patch installer including options available with the latest v4.6, click here. Otherwise, just follow the instructions below.


(Note: This assumes you have already set your HEADAS environment variables with the headas-init script, as you would if you were running XSPEC.)

To make sure your XSPEC installation is up to date with ALL listed patches:

1.    If you don't already have the patch installer tcl script (v4.6), download and place it in the XSPEC src directory. This directory should be at heasoft-[ver]/Xspec/src from the source code distribution.

2.    Download the latest patchfile into the same directory. There is no need to unzip/untar the patchfile since the installer will do that.

3.    At the command line, launch the script by typing 'tclsh patch_install_[ver].tcl', and that's all.


The script should detect which patches you've installed previously, copy the new code files to the necessary directories, determine whether complete or only partial rebuilds are necessary, and finally perform the rebuilds. Numbers listed in red indicate that the patch modifies the interface to one or more of XSPEC's libraries. These patches will generally cause longer rebuilds. If you have a local model library, it is recommended (though not always necessary) that you rebuild it with initpackage after applying red patches.


12.8.2a This adds the noWrite option to the PyXspec AllData.fakeit function. When the argument noWrite=True is passed to AllData.fakeit, fakeit will not generate any output data files. The function signature for AllData.fakeit is now expanded to:

def fakeit(self, nSpectra=1, settings=None, applyStats=True, filePrefix="", noWrite=False)

Report added on Jul 07, 2014.

This patch modifies heasoft-6.16/Xspec/src/XSUser/Python/xspec/ PySpectrum.cxx, .h, and data.py

12.8.2b The time dilation factor was being left out of the zagauss model. This patch also fixes a zagauss array bounds problem that was showing up on Linux platforms. Our thanks to Yuan Liu for pointing this out. Report added on Jul 31, 2014.

This patch modifies heasoft-6.16/Xspec/src/XSFunctions/ calcGaussianLine.cxx and zagauss.cxx
