IUE Image Processing News
NEWSIPS High Dispersion Processing StatusWe 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 The data may be retrieved from the NDADS system once it has been archived, usually just a few days after it has been processed.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 ImagesWe 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 firstname.lastname@example.org). 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!
PublicationsWe 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 (email@example.com) if you would like a copy.
Staff ChangesWe 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.
