intended to inform the numerous remote and local users of the IUEDAC software of recent software
updates, as well as let them know about news relating to the IUE project
IUE Image Processing News
We are continuing to process NASA SWP and LWP low-dispersion data as
they have become available. All 18th episode (and earlier) images are
now releasable and are being processed through NEWSIPS. Sky background
images are now being processed, but not nulls and flat field images.
Some images have not been processed because of missing database
information or other problems. We are currently working on getting those
images taken care of and processed. If you need images that seem
unavailable, please contact Cathy Imhoff (301-794-1470, or
email@example.com). She can check on them and in many cases
fix the problem so that the images can be processed for you.
Work on the software to process SWP high-dispersion images is nearly
completed. We should be able to start processing those images later
this summer. Stay tuned for further developments!

IUEDAC Software Changes (since 01-May-1996):
A new version of the program artifactwas added to the
experimental library which includes the "as yet unpublished"
high dispersion camera artifacts compiled by Crenshaw et al.
The following experimental routines were implemented:
fixes bug which occurs when updating large binary table files
uses the first 3-letters of the file extension to identify NEWSIPS
uses new version of iueftype
compatible with NEWSIPS files and IDL for Windows
uses new iueftype
uses new iueftype and supports NEWSIPS high dispersion files
bug fix for Power Macs
uses node name NDADS rather than NDADSA (which has gone away).
A new version of mxcon was implemented which corrects a
problem which occurred when the new version of iueftype was
installed on May 7th.
The low dispersion sky background files used in the program
artifact have been modified to include data quality flags.
The Copernicus database table has been updated to include the IUE
object classes, and a new version of clog was implemented to
allow searches on this field.
The IUE orbital elements tables (i.e., deltav.lis and
nelements.lis) were updated.
A new version of ifitsrd was installed which corrects a
bug when trying to read multiple rows from an ASCII Table extension.
Warning regarding IUEDAC Routine curestr
Some IUEDAC IDL routines called a program named curestr to
prevent NEWSIPS files from being input before they were officially
released. The original version for example, accepted only SWP low
dispersion images. Any other type of file would cause the program to
Now that high dispersion NEWSIPS data is about to become available, we
have removed the calls to this program. Users who have installed older
versions of the IUEDAC software and who intend to analyze the most recent
Final Archive data, may want to consider either installing a new version
of the IUEDAC software, or commenting out the calls to this routine. The
programs affected include readmx, readri,
readli, readsi, boxcar,
bspot, coadd, gex,
iueread, lblfix, rdim,
rdstds, and rdz.
