New issues from Xspec 12.5.0
For those linking the XSPEC models library into their own programs, the
XSFunctions library now has new dependencies on libXSModel and libCCfits, requiring that they
be linked into your program. See manual
Appendix F for more details.
We recommend avoiding the X11 2.3.1 upgrade on the Mac OS X Intel platform,
as it prevents PGPLOT's /xserve driver from properly refreshing the plot window. This
problem has been fixed in the X11 2.3.2 release candidate versions. Our thanks to Terry Gaetz
for pointing this out.
Frequently Asked Questions
List of currently outstanding issues.
Patches:
HEASOFT 6.6.2 is distributed with XSPEC12 already patched to version 12.5.0ac.
latest update
12.5.0ag May 08, 2009
Requires patch installer v2.5 or
newer
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 new options available with the latest v3.0, 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 (v2.5 or later), 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.

When the editing commands addcomp, delcomp, or editmod

link expressions are not properly updated in the output to a save model
file. Our thanks to Laura Brenneman for pointing this out.

This removes the warnings issued if datasets contain CHANTYPE strings other than
PI or PHA. It will still issue warnings if the CHANTYPE differs between
the spectral data and RMF files.

Additional C/Fortran function wrappers provided for the following recently added C++ models:
cflux, partcov, simpl, and spexpcut. These are required for users who
link the XSPEC models library into an external Fortran or C program.

In the FNINIT function (for users linking the XSPEC models library into their own programs), the default
model data directory name needs to be updated from "modelIonData" to "modelData" to coincide with
v12.5.0 restructuring. Our thanks to John Houck for pointing this out.

Patch to improve the behavior of an exceptional case of Levenberg-Marquardt
fitting, where a parameter becomes pegged due to a zero second-derivative matrix diagonal element AND
the user chooses to exit before convergence.
This prevents an attempt at a covariance calculation on the parameter, which otherwise might lead to a segmentation fault.
Our thanks to Stefano Bianchi and Jeremy Sanders for pointing this out.

Fix to the swind1 model function. Now that it is included
as part of XSPEC's built-in models library, it should no longer look to
the $LMODDIR symbol for finding the model data directory.
Our thanks to Delphine Porquet for pointing this out.

Parameter links both to and from a model which is not associated with any
spectra (shown as "Active/Off" in the model display), should not be removed when
the model's state gets updated (such as when using the dummyrsp command). Our thanks

This slightly modifies the state of newly untied parameters.
When a parameter is untied, its frozen/unfrozen setting should
retain the setting of the parameter(s) to which it was linked, rather
than be restored to its original value. Our thanks to Phil Evans and Delphine Porquet
for pointing this out.

When steppar is executed, it should not automatically run a fit
at the end to place the parameters in their best-fit state. Instead it should
restore the parameters to their pre-steppar values, regardless of the fit state.

Bug fix for a C-to-Fortran boolean conversion error, affecting the
default setting for the thermal broadening flag of the bapec
and bvapecmodels. Unless overridden by the APECTHERMAL setting,
thermal broadening should be ON by default for bapec and bvapec.

This adds an option for choosing Y-axis units when plotting in
setplot wave mode. The selection is made by the WAVE_PLOT_UNITS entry,
which has been added to the new version of the Xspec.init file.
The units may now be specified in Hz (the default for version 12.5.0),
or angstroms as they were prior to 12.5.0. This applies to plots of data,
counts, and all variants of model and ufspec plots.

A new tclout option has been added to make it easier to retrieve the fit
parameters' sigma values. The syntax for this option is:
tclout sigma [< modelName>:]n
where n is the parameter number. If it is not a variable parameter or if the
fit was unable to calculate its sigma, a value of -1.0 is returned.

Fixes to a couple of obscure cases of gain parameter usage:
If a gain parameter belongs to a response temporarily replaced by a
dummy response, or a gain parameter is indirectly removed through the data
command erasing its associated spectrum and response, the gain shift may still
be applied to a response occupying its former spectrum and source number. This patch also
improves the show response output.
