New issues from Xspec 12.9.0

Frequently Asked Questions

List of currently outstanding issues.


latest update 12.9.0d Aug 31, 2015

Requires patch installer v4.7

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 v4.7, 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 (v4.7), 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.

12.9.0a This fixes a bug in the calculation of agauss/zagauss models. Our thanks to Doug Burke for pointing this out. Report added on Aug 05, 2015.

This patch modifies heasoft-6.17/Xspec/src/XSFunctions/ calcGaussianLine.cxx

12.9.0b The (b)vvapec model calculation exits early with an "Unrecognized value of itype" error. Our thanks to Doug Burke for pointing this out. Report added on Aug 06, 2015.

This patch modifies heasoft-6.17/Xspec/src/XSFunctions/ smdem2.cxx

12.9.0c If a link expression is entered during the parameter prompting stage when initially defining a model, AND the link uses the new 'p' format specifier AND the link is to a parameter within the same model and data group, XSPEC will improperly reject the link as invalid. Note: This is mostly likely to occur when reloading a model from an XSPEC save file, as save files now use the 'p' format when storing link expressions. Our thanks to Kenji Hamaguchi for pointing this out. Report added on Aug 14, 2015.

This patch modifies heasoft-6.17/Xspec/src/XSModel/Parameter/ ParameterLink.cxx

12.9.0d The lmod command is not working when called from an xspec.rc start-up file. To load local models from the .rc file, XSPEC is requiring that you use the Tcl 'load < /path/to/ >' command rather than the lmod shortcut. Our thanks to Eric Miller for pointing this out. Report added on Aug 31, 2015.

This patch modifies heasoft-6.17/Xspec/src/XSUser/Handler/ xsLmod.cxx
