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 RECOGNITION CEREMONY- 11AM FRIDAY 29 SEPTEMBER 
1995



        
 In recognition of 17 years and 8 months of extraordinary service 
 to the astronomical community and the successful efforts to 
 streamline ground operations,  Drs. Joe Rothenberg, Director of 
 the Goddard Space Flight Center,  Daniel W. Weedman, Director of 
 the Astrophysics Division at NASA, and Yoji Kondo, IUE Project 
 Scientist, will acknowledge the unique role of this first All-
 Guest-Observatory satellite facility in a formal ceremony of appre-
 ciation.  We at NASA hope that you can join us in person to 
 acknowledge this special achievement.  The proceedings will be 
 held at Goddard Space Flight Center (the home of IUE), Building 
 21 Room 183, on Friday, 29 September 1995 at 11 am.          

 The International Ultraviolet Explorer (IUE) project "keeps on 
 going" in the continuing spirit of the little satellite that 
 could.  The project has reconfigured its science and satellite 
 operations to reduce costs.  On 30 September 1995, the US IUE 
 team will turn over science operations to the ESA ground station 
 at Villafranca, where the ESA/PPARC teams will continue to con-
 duct astronomical observations on behalf of the international 
 astronomical community.  The US team will provide streamlined 
 support for satellite operations and will continue their task
 to complete the IUE Final Archive that contains over 
 100,000 ultraviolet spectra.
        
 If you plan to be with us for this event, please send us a quick 
 message by email so we can plan for your attendance.  If you 
 cannot be with us in person, you are cordially invited to send 
 your messages expressing your sentiments for a job more-than-well 
 done to the following electronic mail address.

 IUEDAC SOFTWARE AND HARDWARE UPDATES 

Recent System Changes:

    9/1/95  - IDL 4.0.1 was installed as "IDL". "IDLV2" and 
              "IUERDAF" currently still point to IDL 3.6.


Recent Software Changes:

22-Aug  The following routines from the experimental library 
        were implemented:
         kurget     correct error in model spacing
         kplist     command line search routine for kandp
         kurget1    corrected for variable spacing of high 
                    Temp models
         iuelib     adjust !y.margin for PCs
         ipinfo     correct errors when dir = 'NA'
         ipi_lisi   change search for NEWSIPS processing 
                    dates
         dosplat    set dir = 'NA' for PCs
         platform   define win32 like windows (for IDL 4.0)
         ifitswrt   allow comments & new input parameter 
                    options
         nsplot     allow modifying plot titles
         convert    doesn't require standard iuedac file 
                    names
         unred      added tabfile keyword
         fes2v      converts fes counts to visual magnitudes
         stdsfile   supports newsips standard star spectra
         rdstds     extracts data from newsips standard star 
                    spectra
         mlog       a non menu-driven merged log search 
                    routine
         clog       a non menu-driven copernicus data-base 
                    search routine
         alias      subroutine of clog for accessing ALIAS 
                    database table

25-Aug   A new version of kurget1 was implemented which 
         correctly handles the variable spacing of Kurucz 
         models at high temperatures.

11-Sep   A bug was corrected in the implemented version of 
         IFITSWRT.

 IUE IMAGE PROCESSING NEWS 


IUESIPS REPROCESSING
 

As the IUE 18th episode draws to an end, so does our 
processing of IUE images through IUESIPS.  As of the 
beginning of September, NO MORE REPROCESSING OF ARCHIVAL 
IUE DATA WILL BE PERFORMED USING IUESIPS. Note that this 
affects IUESIPS only.  The reprocessing of archival
data through NEWSIPS to create the IUE Final Archive 
will continue.

We will process the requests in hand, and of course 
all 18th episode NASA data taken through the end of 
September. Since we have received very few requests 
for archival IUESIPS processing, we don't expect this 
to affect our Guest Observers. However, if you believe 
that this will be a severe problem for your research, 
please contact us as soon as possible. 

IUESIPS STATUS
 

Over the last several weeks, we accumulated a large 
backlog of images to be processed through IUESIPS, 
largely due to problems with our ancient image display 
device. The IPC staff have been working hard to reduce 
the backlog. At present the backlog is equal to about 
1 weeks worth of processing.  If you have any questions 
about your recent images, please contact Cathy Imhoff 
(301-794-1470 or imhoff@iuegtc.gsfc.nasa.gov). 

NINETEENTH EPISODE PROCESSING

VILSPA will be processing all 19th episode data.  

NEWSIPS STATUS

We are now processing LWP low-dispersion images taken 
after 1990. We should complete the available images 
in the next two or three weeks.

VILSPA has finished processing their SWP and LWP 
low-dispersion images taken before 1990.  We have 
received a shipment of LWP tapes, and NSSDC will 
be working on adding the data to the NDADS system.  
We will announce when the data become available.

IUE DATA MANAGEMENT CENTER (DMC)

After all the 18th episode data acquired at the IUE 
GSFC observing station has been processed and 
distributed to the appropriate IUE Guest Observers, 
the functions of the IUE Data Management Center will 
be merged with other areas as appropriate and the DMC 
will cease to exist.  Any questions that would have
normally been addressed to the DMC can still be sent 
to Karen Levay 301-794-1440 or levay@iuegtc.gsfc.nasa.gov.

GSFC is no longer rehabbing 9-track tapes for reuse.  
Due to lack of funds the IUE Project is no longer 
able to pay for tapes to be returned to GSFC.  
Therefore, Guest Observers are encouraged to find 
appropriate ways to reuse the 9-track tapes 
at their home institutions.

OLD USER ACCOUNTS ON TAPE

The IUE Data Analysis Center has VMS Backup tapes 
for its USER accounts  dating back to 1988. Those 
older than September 1994 are 9-track tapes. We 
are planning to discard these old 9-track tapes 
in December (1995). Users who want their files 
restored from these tapes should contact us  before 
that time.  This pertains only to accounts USER1 
through USER60 at the times that these accounts 
were recycled (i.e., backed up and then cleared 
for disposition to new users).

JUST FOR FUN
 

Anyone wish to hazard a guess on what IUE's odometer is 
reading these days? 

If you consider just the spacecraft's orbit around the 
Earth since launch, IUE has travelled almost 11 A.U. - 
about 1 billion miles! 

If you include the motion of the Earth and IUE around the 
Sun, you can add in another 110 A.U.
