IUE DATA ANALYSIS CENTER NEWSLETTER
This is an electronic newsletter edited by the IUE Data
Analysis Center (IUEDAC)intended to inform the numerous remote
and local users of the IUEDAC software of recent
software updates and project changes.
IUE 19th EPISODE!!!!
NASA, ESA and PPARC are pleased to announce the 19th
observing episode of the International Ultraviolet Explorer
(IUE). The 19th episode will place emphasis on key science
programs, allocating time to those projects determined to
produce important and lasting science. We estimate that
approximately half of the available time will be awarded
to key projects for the FULL year of observations. Time
will also be allocated for moderate shift requests as well
for the 19th episode if the science is determined to be
important. The episode will start on or around 1 October
1995 and end 30 September 1996 for the NASA science program.
ESA/PPARC is considering an extended mission beyond 30
September 1996, but it is very unlikely that NASA will
participate in that phase of operations.
Copies of the International Ultraviolet Explorer 19th
episode proposal package are now available in the
pub/proposal subdirectory of the anonymous ftp
account on iuesn1.gsfc.nasa.gov. The proposal
instruction package is available in either word perfect
format (pip19.wpf) or ascii text format (pip19.txt).
Associated files available in the same directory are described
in the README file. The proposal package can also be
accessed via the IUE Data Analysis Center home page on
the World Wide Web and hardcopies are available from the
IUE project by contacting Mona Drexler at (301) 286-7664
or drexler@iue.gsfc.nasa.gov.
As mentioned before, proposers should note important
changes in the manner and mode the observatory will
operate after 1 October 1995 due to a significant
reconfiguration of the ground system that will be
implemented in order to lower operations costs.
Please note the following important dates concerning
proposal submission:
Proposal due dates: COB 22 May 1995
IUE observing peer review: July 1995
Proposal Selection and notification: July 1995
Approximate Beginning Date for 19th Episode: 1 October 1996.
For more information please contact Dr. Donald West,
IUE Operations Scientist at (301) 286-6901, or
Dr. Andrew Michalitsianos (301) 286-6177, or by e-mail

SURVEY OF DEGREES EARNED WHICH MADE USE OF IUE DATA
The IUE Project wishes to update its statistics on the number
of degrees which have been earned with studies using IUE data.
If you or your students have earned degrees at any level where
your study involved the use of IUE data, we would appreciate
you sending the following information to us.
The name of the person earning the degree.
The degree.
The institution from which the degree was earned.
The year the degree was conferred.
We are attempting to get as exhaustive of a list as possible,
and will be sending this message out periodically over the
next few months. Any help you can provide us to obtain this
information will be greatly appreciated. You can send us this
information by replying to the source of this email notice
(news@iuedac.gsfc.nasa.gov), by calling (301) 286-7762, or by
sending a note to:

IUE IMAGE PROCESSING NEWS
HOORAY! We have begun process Goddard SWP low-dispersion
images taken after 1990. Note that we can process only
images which are no longer proprietary; the image number
cutoff is about SWP 52900 (December 1994).
You are welcome to request specific images that you need
for your research; they will be processed as soon as possible.
The output files will be sent to NSSDC and made available
through the NDADS system. Please use our new request procedure
to insure that your request is handled promptly.
There are 3 ways to send us a request.
(1) You can use the IUEDAC routine USRREQ. Enter USRREQ,DUMMY
and you will be prompted for the input.
(2) You can send a request from the World Wide Web. If you
perform a search of the IUE Merged Log on the WEB, you
have the option to request NEWSIPS processing. The IUEDAC
homepage has a link to the request form, or you can go directly
to the Request form at
http://banzao.gsfc.nasa.gov/IUE/search/IUE_usrreq.html
(3) You can send a formatted e-mail message directly to
usrreq@iuegtc.gsfc.nasa.gov, with the following (sample) format:
NAME Joe Astronomer
EMAIL_ADDRESS joe@some.computer.edu (please use Internet format)
PHONE 555-555-5555
SPONSOR University of Hard Knocks
REPRT/PROCESS P (P = process, R = report)
IMAGELIST
SWP12345L (don't forget the dispersion)
LWP09876L
ENDOFLIST
Enter P to request processing under the keyword REPRT/PROCESS.
Or you can try out our new report feature; enter R to request a
status report on the images. In either case, you will receive
an e-mail message back noting which images have already been
processed, which are queued for processing, and which can't be
processed at this time. Note that the keyword entries for
NAME etc. start in column 15. Also please break up long requests
into smaller ones, containing no more than 50 images per request.
Sometimes images will be listed as not ready for processing.
Feel free to contact Cathy Imhoff (imhoff@iuegtc.gsfc.nasa.gov,
or 301-794-1470) for information about such images.
Processing of the SWP and LWP low-dispersion Part 1 images
(pre-1990) is essentially complete. Nearly all the data should
now be available from the NDADS system for Goddard images. These
data include SWP images up to image number 37929 and LWP images
up to 17058. If you are not familiar with the procedures for
retrieving data from NDADS, please contact the IUEDAC staff for
help.

IUEDAC SOFTWARE AND HARDWARE UPDATES
Recent Software Changes:
02-May The following routines were implemented:
IUESPEC - allows for flexible input file
names (i.e., doesn't require
standard "imaget" file names)
READFILE - corrects error in optional
isize parameter
DATAREC - properly reads GO files on MACs
and PCs
RDAFTOGO - new routine for converting rdaf
format files to IUE GO format
IMFITS & EXTFITS - corrects error in wavelength
assignments when converting
iuesips files to FITS format
05-May A new version of USRREQ was implemented to allow
users to request reprocessing of post-1990 LWP
and SWP low dispersion images (using NEWSIPS),
and to determine the status of NEWSIPS reprocessing
requests. Use DOC_LIBRARY,'USRREQ' for more information.
08-May Obsolete data sets that were stored in
iue$user1:[iuerdaf.iuelib.dat] have been moved to
iue$user1:[iuerdaf.obsolete.dat]. All the moved
files (and the IUEDAC routines which use them) were
rewritten to use FITS format. See a member of the
IUEDAC staff if any problems arise.
12-May A new version of NEWCALIB has been implemented
to support the calibration of post-1990 SWP low
dispersion spectra. This will allow routines such
as GEX, MGEX, and BOXCAR to extract calibrated
fluxes from these images.
12-May A new routine called MPATH was implemented to allow
users to modify the IDL search path. Use DOC_LIBRARY
for more information.
