RELEASE NOTES FOR SAO/PROS 2.5 -- October 97
PROS 2.5 has been built under the IRAF V2.11 system, with the package
TABLES/STSDAS version 2.0. There is now full support for Solaris
platforms running PROS, and binary executables for both Sun operating
systems are released.
The xray package is a "top level" package (at the same level as packages
such as "tables" and "noao"). The xray package contains the sub-packages
xdataio, ximages, xspatial, xspectral, xplot, xtiming, xproto, xinstall
and xdemo.
I) Setting up to use the XRAY package
To run the xray package, sites should use the default IRAF V2.11
(V2.10 for non-Sun sites).
In addition, the TABLES 2.0.Beta package, available from STScI, is
required. Optionally, the EUV package is used by the XPROTO/TABFILTER
task and is available from "cea-ftp.cea.berkeley.edu" (128.32.154.12).
Users must rerun the "mkiraf" task and answer 'yes' to the
're-initialize uparm?' option before running.
II) Summarize the changes made in PROS 2.5
**** NEW TASKS ****
< package.subpackage.task - descriptions >
xdataio.qpappend_ftsi - Append a list of input qpoes to produce
a single qpoe file. It is similar to qpappend except that it
has a new parameter that gives the user the control of whether
or not to append the TSI records. Either all or just the first
TSI records can be included in the final qpoe file.
xdataio.rarc2pros_c - Convert ROSAT archive fits files into
a set of IRAF/PROS files. It is similar to rarc2pros except
that it works for filenames whose extensions are capitals
(eg. root_BAS.FITS).
xproto.imdetect - A new task "imdetect" has been cloned from
SASS processing. It uses a fixed background level instead
of the local detect algorithm adopted in 'ldetect'. It
can work for ROSAT data or ASC (AXAF Science Center) data.
See the help file for more details.
**** BUGFIXES AND ENHANCEMENTS ****
< package.subpackage.task - descriptions >
xdataio.qpappend -
- Updated to solve the crash problem when merging qpoe's with
different TSI formats. Instead, a new qpoe is now created.
- Updated to write DATE-OBS,TIME-OBS,DATE-END,TIME-END as
character strings.
ximages.qpsort -
Increase the length of prosdef_out for XS-EVENTS to solve
the problem of the table columns truncated.
xplot.imcontour and xplot.tvimcontour -
Updated to check whether wcs params are available from header.
xspatial.imcnts -
Updated to display the count in a correct data type.
xspatial.detect.imbepos -
Display a warning message when input is not in a QPOE format.
xspatial.ximages.imcalc -
There are two imcalc's one in stsdas and one in xspatial.
If packages were loaded in the wrong order then the wrong
imcalc could be called from scripts. We have changed all
the PROS tasks that use imcalc by making the call explicit
('ximages.imcalc') to preclude the previous ambiguity.
xspectral.hxflux -
Check the range of requested output energy and display an
error message if it's outside the acceptable range.
xtiming.ksplot -
The plot was scaled and labelled incorrectly when running
ksplot more than one time. Now it has been fixed so users
do not need to log out of iraf to get another plot.
xtiming.timcor.apply_bary and xtiming.timcor.scc_to_utc -
These two tasks were updated to read the column name
NCOE from scc_to_utc.tab instead of the name NCOEFF.
Therefore, the table released from MPE can be read directly
from these tasks without any pre-conversion.
xtiming.timcor.calc_bary -
Updated to read the jdleap table as a floating point instead
of an integer. Also, it now read the table column "JD" instead
of "JDLEAP" to match up with the column name released from MPE.
xinstall.fits2spat -
Added a pathname to hdummy qpoe and moved the call to
datarep to the end.
qpcreate_lib -
Updated to have only one qpcisqpoe.
**** THE UPDATED CALIBRATION DATA ****
<xpackage.data : description >
xspatial.data : hri_qegeom.imh (see H&P18)
Updated to correct the problem in PROS 2.4.
xtiming.data : jdleap.tab (see H&P19, H&P20)
A new version of the Julian Day/leap second file through
1-Jul-1997. The data type is now changed to DOUBLE.
xtiming.data : scc_to_utc.tab (see H&P19, H&P20)
Coefficients for the conversion of space craft clock time
to UTC have been updated by MPE. These values are valid
through 8-Jun-1997.
**** TASKS UPDATED FOR ASC AND THEIR TEST DATA ****
< package.subpackage.task - descriptions >
xproto.imdetect - A new task.
xdataio.fits2qp and xdataio.qp2fits -
- Updated to do the fits and qpoe conversion.
- two new cards: qpoexrcf.cards and wcsxrcf.cards
xspatial.detect.lpeaks -
Commented out error when xdim != ydim; found no dependence in
code when tested; required for AXAF gratings detection.
pros_lib -
xhead - Added new keywords to the qpoe header for ASC.
qpcreate - Added check whether the input file is QPOE format.
qpwcs - Updated to skip writing wcs when info unavailable.
xhist - Added two new routines for this program to allow table
files as input.
ASC data -
ASC data samples for imdetect and fits2qp/qp2fit are in
xspatialdata.
**** UPDATED FOR ARCHITECTURE ****
xray.mkpkg - added Alpha and Linux architectures
ximages.qplintran, xtiming.fft and xdataio.eci_tools (see hp#19)
updated to fix the problems when building xray on Linux.
**** CHANGES MADE FOR IRAF 2.11 ****
xray.lib - mkpkg.inc
- add xray package name to the compile flags
xplot.xexamine -
IRAF2.11 has fixed the inconsistency between the QPOE
and IMAGE coordinate systems. Therefore, the factor of
0.5 pixel is no longer needed in xexamine.
xplot.<scripts> -
scripts in XPLOT that use the DISPLAY from IRAF have been
updated to accommodate the IRAF2.11 release
Updated some codes to distinguish between INDEFD and INDEFR
III) Other Information
A. PROS User's Guide (PUG) ( revised on 5 December 1996, see hp#20)
Latex and/or postscript files are available via anonymous ftp:
sao-ftp.harvard.edu; from subdirectory /pub/pros/PUG.
The WWW version can be accessed with URL:
http://hea-www.harvard.edu/PROS/pros.html
B. Cross-referencing infomation
We are continually trying to improve the cross-referencing information
in PROS. We recommend using either "references" or "xapropos" to look
for information on given keywords, e.g., "references prf" or
"xapropos prf" (xapropos requires the CTIO package to be loaded).
C. Hints & Pointers
As the provider of the PROS software package ("xray" in IRAF), the
ROSAT Science Data Center (RSDC) at SAO distributes HINTS & POINTERS
to PROS Users via email. When we find answers to often asked
questions, or when we have implemented new software solutions to
longstanding problems, we will send this information directly to our
users. These messages will also be available via anonymous ftp*, but
to receive the email version, you should register with us. If your
username is the one associated with your site registration, you are
already registered for "HINTS & POINTERS", but we encourage other
users (even at the same sites) to register.
Mailings will be sent as the need arises, perhaps every month or so.
If you would like to suggest items for future issues of H&P or add
your name to our distribution list, please contact us at the following
