12.7.1d Jul 11, 2012
Requires patch installer
v4.2
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 v4.2, 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 (v4.2), 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.

XSPEC is rejecting response files whose EBOUNDS extension is missing
a DETCHANS keyword. In this case, XSPEC should just assume DETCHANS
equals the number of EBOUNDS rows. Our thanks to Mike Corcoran for pointing this out.

When doing multi-panel plots of plot chain, the
parameter arguments for the last chain plot are being sent to each of the plots.
This patch also improves the error handling in the plot chain and
plot model commands. Our thanks to Jose Martí for pointing this out.

This adds a new thin option to plot chain, for plotting Monte-Carlo Markov chains.
When thin < N > is inserted into a plot chain command, only 1 out of every
< N > chain points will be displayed in the plot. Example usage:
# plot one in five chain points, using parameters 1 and 4 for (X,Y)
XSPEC12>plot chain thin 5 1 4
The thin value will be retained for future chain plots until it is reset. Use thin 1
to remove thinning. Our thanks to Jeremy Sanders for this suggestion.

This adds new ways to retrieve the list of ignored channels, in both standard XSPEC
and PyXspec. In standard XSPEC this is done with the new tclout ignore < N > option,
where < N > is the spectrum number.
In PyXspec, there are now 2 additions to the Spectrum
class: an ignored attribute and an ignoredString() function. The former returns a Python list
object containing every ignored channel number. The latter returns the same information in convenient
string form, which can be reused as input to a future ignore or notice command. Our thanks to
Terry Gaetz for this suggestion.
