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.
