There are two bugs in fakeit. If there is
no background file in use then the BACKFILE command in the faked
file is set incorrectly. The workaround is to change the keyword to
'NONE'. The value of the fit statistic written to the screen by the
fakeit command is wrong. The workaround is to follow the fakeit
command by newpar 0. Bug report added on Jun 24, 2002. Note that this
fix has been superseded by 11.2.0i.

| 11.2.0j |
The cooling flow models produce no
flux. The reason is that the cosmological parameters are not
initialized to non-zero values. The workaround is to use the cosmo
command to set H0 (and optionally q0 or lambda0). Note that the
fix below initializes H0=50, q0=0, l0=0. Our thanks to Jeremy
Sanders for reporting this. Bug report added on Aug 6, 2002.
The fix is to replace
spectral/xspec/src/COMMAND/xsstrt.f

Integral IBIS files do not work in XSPEC
due to a certain laxity in applying the standard. This fix allows the
nth spectrum in the file to be accessed by filename{n} as though the
file was in the standard type II format. A similar fix for the ARF is
included. Bug report added on Sep 13, 2002.

There are three minor problems with saved command files : if the model
string is too long it will be split into separate lines which cannot
then be reread by xspec; any string parameters specified by xset are
not written out; cornorm commands are written out even if no
correction file is in use. These bugs were reported by Ian George,
Marc Audard, and David Buote, respectively. Bug report added on Oct 2, 2002.

| 11.2.0aa |
The help files for xspec and plt cannot both be accessed in the same
xspec session. If the help command is invoked from the xspec
prompt then subsequent invocations from the plt prompt (after iplot)
will give help for xspec and not for plt. If the plt help is accessed
first then that is what appears when the xspec help command
is invoked. Thanks to Ilana Harrus for reporting this. Halloween bug report

|
| 11.2.0ah |
In an attempt to reduce compute time XSPEC doesn't recalculate models
for any datasets with identical energy ranges to an earlier
dataset. This is fine except for models that actually use the IFL
argument and treat each dataset individually. There are no standard
models which do this but users may run into this issue when writing
local models. The slightly ugly workaround is to read each dataset in
a separate datagroup. Thanks to Jeremy Sanders for reporting this.
Bug report added on Dec 17, 2002.
|
| 11.2.0ai |
The net errors can be (obviously) incorrect if changing to a
non-standard weighting (eg gehrels) for a dataset without a

The tclout plot contour command doesn't write out all the values in
the steppar run. Bug report added on Feb 5, 2003.
The fix is to replace
spectral/xspec/src/PLOT/xpltit.f.
Note that the tclout output is not in the same order as the steppar
list because steppar switches direction on the parameters stepping fastest.

The tclout flux and eqwidth commands take the dataset number as an
argument not the datagroup number. There was also a bug that the
valid argument range was based on datagroups not datasets. Thanks

The fix is to replace
spectral/xspec/src/COMMAND/tclout.c
and
spectral/xspec/help/xspec.hlp
|
| 11.2.0ao |
Mega-patch of bugs and some small new features that have been
requested. Includes: a) fixed setplot dev none; b) fixed projct model so
it works correctly for multiple observations ie more than one dataset
per datagroup; c) added fstat and query options to tclout to return
information on results of last ftest command and current setting of
the query; d) if steppar has been performed on only one parameter then
plot contour produces a 1-D plot; e) the model description written out
can now be cut and paste to use in the model or editmod commands.
Bug report added on Feb 7, 2003.
Modified Feb 24, 2003 - the wrong versions of tclout.c and
xscf.h were included in the tar file.
The fix is to use the latest patch file,
uncompress and rebuild XSPEC.

| 11.2.0ap |
The command fakeit filename does not work correctly. If no
previous dataset has been read it creates fake source and background
files with zero counts and if a previous dataset has been read then
it uses the backscal and areascal from this dataset instead of from
the filename specified in the fakeit command. Our thanks
to Allyn Tennant for reporting this. Bug report added on Feb 16, 2003.
The fix is to replace
spectral/xspec/src/DATA/gtfkfl.f

| 11.2.0au |
The bug fix to reflct in 11.2.0t introduced a new bug that causes the
calculated amount of reflection above 10 keV to be smaller than it
ought to be. The effect of this can be seen by comparing
reflct(cutoffpl) with pexrav. Thanks to Andrzej Zdziarski and Piotr
Lubinski for diagnosing this. Bug report added on Mar 17, 2003.
The fix is to replace
spectral/xspec/src/functions/reflct.f

acisabs and compps models. Bug report added on Mar 18, 2003.
The fix is to follow these instructions.
|
| 11.2.0aw |
There are several points to watch out for when using the error option
on the flux or lumin commands. The model cannot be changed (using
model, editmod, addc, or delc) between doing a fit and flux/lumin with
errors. If a parameter is changed, eg the absorption column set to
zero, the realizations used to estimate the error will vary the
parameter around its new value but with a variance from the last fit.
Bug report added on Mar 28, 2003.
|
| 11.2.0ax |
There is an error in the cooling flow models (cflow, mkcfl, vmkcf)
causing incorrect weightings to the emission measure at the extremes
of the temperature range. The main effect seems to be an approximately
10% error in the normalization. Thanks to Dave Smith for spotting this.
Bug report added on Mar 28, 2003.
The fix is to replace
spectral/xspec/src/functions/xsvcfl.f.
The old model is available using the XSPEC command xset
cflow_version 1. The new version is the default and can be set by
xset cflow_version 2. The new version also allows the number
of temperature steps in the integration to be varied. The default is
10 and can be changed by eg xset cflow_ntemps 20. Note that
changing the number of integration steps will have little practical
effect unless switch=0 in the mkcfl or vmkcf models.

When using parameters whose maximum is not equal to their top or
minimum is not equal to their bottom it is possible for apparent
parameter values to swing between maximum and minimum but for the
model itself not to change. One diagnostic of this can be that
saving a model then later reading it back in will give very different
values of the fit statistic and a clearly incorrect fit. Our thanks
to Phil Evans for reporting this. Bug report added on Sep 22, 2003.

The fix is to replace
spectral/xspec/src/functions/projct.f
and rebuild XSPEC.

The thleqw command doesn't work. Our thanks to Dirk Pandel for
pointing this out. Bug report added on Oct 23, 2003.
UPDATE: Error in xscmnd.f corrected on Oct 24, 2003
The fix is to replace
spectral/xspec/src/DATA/calpht.f,
spectral/xspec/src/MODEL_COMP/calcon.f,
spectral/xspec/src/COMMAND/xscmnd.f,
spectral/xspec/src/RESPONSE/dmyrsp.f
and rebuild XSPEC.

The component plots produced after "setplot add" are slightly wrong
for models of the form A1 + M1(....). The plot of the A1 component is
actually of M1*A1. This does not effect the fit or plot of total
model. Our thanks to Frank Haberl for reporting this.

Platform-Specific Problems:
SGI/IRIX 6.5
XSPEC may hang on started when run remotely through ssh. This appears to be a problem
with ssh's setting for the DISPLAY variable.
Workaround: set display manually before starting XSPEC on a remote SGI host through
a secure shell.
OSF 4.0D
XSPEC v.11's scheme for linking to local models does not work on OSF as yet, owing
to the way OSF sets dynamic link paths. We hope to resolve this problem in the near
future. There are two possible workarounds:
- Build the local models into xspec when the main build and install is performed.
- Build the local models as per the instructions for other platforms, but move aside the
default local models library, $LHEASOFT/lib/libxspec_lfn.so (e.g. to $LHEASOFT/lib/libxspec_lfn.so.save).
All users will, however, have to supply a correct path for the locally constructed models
library.
