IUE Image Processing News
NEWSIPS High Dispersion Processing Status
We have now processed over 2/3 of the NASA SWP high-dispersion images
through the NEWSIPS system. These have been processed with the final
version of the extraction slit and associated ripple correction. For the
first month we were processing images with a somewhat preliminary
extraction slit and ripple correction. Please be aware that these earlier
processed images (before October 11) may differ somewhat from the final
version. If you have some of them, you should obtain the later version
from the IUE archives.
You are welcome to send us a list of your favorite images to priority
process. There is a NEWSIPS user request Web page at http://hypatia.gsfc.nasa.gov/IUE/search/IUE_usrreq.html.
Your request goes into a semi-automated system, which will send you email
reports on the status of the processing. The data may be retrieved from
the NDADS system once it has been archived, usually just a few days after
it has been processed.
We will have the capability to process LWP high dispersion images in the
next couple of months. We will then add the capability to process LWR
high dispersion images in the following couple of months. Processing of
all images for the IUE Final Archive is to be completed by the end of
September 1997.
NEWSIPS Status For Low Dispersion Images
We have continued to process NASA SWP and LWP low dispersion data as they
have become available. Out of over 38,000 images, 91 percent have been
processed and are available from the NDADS system. The remaining
unprocessed images include flat field calibration images and images which
have not been processed because of missing database information or other
problems. We are currently working on getting those images processed. If
you need images that seem unavailable, please contact Cathy Imhoff
(301-794-1470, or imhoff@iuegtc.gsfc.nasa.gov).
She can check on them and in many cases fix the problem so that the images
can be processed for you.
VILSPA is also processing their LWP and SWP low-dispersion images and
delivering them to us. As they are received they are being placed into
the NDADS system.
We will have the capability to process LWR low dispersion images later
this spring. Stay tuned for further developments!
Publications
We have copies of the NEWSIPS Processing Information Manual
available (describing SWP and LWP low dispersion). We also have copies of
the IUE Spectral Atlas, published as NASA IUE
Newsletter No. 43, and some back issues of newsletters. Please
contact Cathy Imhoff (imhoff@iuegtc.gsfc.nasa.gov)
if you would like a copy.

Staff Changes
We neglected to mention the departure of Michele De La Peña from the
project a couple of months ago. She has moved on to the Science Software
Group at the Space Telescope Science
Institute. We thank her for her years of dedicated and excellent work
for the IUE project. We wish her the best in her new work, and offer our
apologies for the omission.
