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.





 
CHANGE IN ANONYMOUS FTP AND WWW ADDRESSES 


The IUEDAC has recently completed the transfer of 
all anonymous FTP and World  Wide Web files to a new 
machine, iuewww.gsfc.nasa.gov.  The new machine, a 
Sparc 20, provides more file storage space and faster 
service than the Sun 4/280 it replaces.  For anonymous 
FTP service, there are no changes other than the machine 
name; the directory structure and files available have been 
preserved. The WWW pages are slightly different, since 
we took advantage of the system change to clean up the 
directory structure.  The following URL's replace those 
frequently used on iuesn1: 

   IUE Project Home Page:

        http://iuewww.gsfc.nasa.gov/iue/iue.html
        
   IUE DAC:  

        http://iuewww.gsfc.nasa.gov/iue/iuedac.html
        
   IUE Operations:  

        http://iuewww.gsfc.nasa.gov/ops/iuetoc_homepage.html
       
The links on these pages point to the new locations of 
the files available. If you have any trouble accessing 
either the FTP or WWW files, feel free to  contact either 
Jim Caplinger at caplingr@iuewww.gsfc.nasa.gov or Dr. Michael
Carini at carini@iuedac.gsfc.nasa.gov.

SURVEY OF DEGREES EARNED WHICH MADE USE OF IUE DATA

The response to our request for information on the number 
of degrees which have been earned with studies using IUE 
data has been fantastic. Thank you to all those who have 
already responded. If you have not yet responded, and 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:

  NEWSIPS STANDARD STAR SPECTRA NOW AVAILABLE ONLINE

The IUEDAC online archive of IUE low dispersion standard 
star spectra (as described by Wu et al in IUE Newsletters 
#22 and #43) is being updated to include the corresponding 
NEWSIPS-processed MXLO files. The NEWSIPS data will be 
particularly useful for users who need to determine spectral 
types of NEWSIPS-processed spectra. Approximately 75% of the 
468 LWP and SWP spectra have now been loaded. The LWR files, 
and the remaining LWP and SWP MXLO files, will be added as 
they become available. Two IDL routines have been modified to 
allow users to locate and display both iuesips and newsips 
standard star spectra. STDSFILE lists the available images
for a given spectral type. For example, STDSFILE,FLIST,'B3',/NEWSIPS 
will store the names of all NEWSIPS standard star spectra of 
spectral type "B3" in string array FLIST. RDSTDS will read and 
extract the data from the specified input file 
(e.g., RDSTDS,FLIST(0),H,W,F,NU will extract the data from 
the first "B3" file returned in the STDSFILE example above.) 
The online archive is also useful for users simply interested 
in comparing IUESIPS and NEWSIPS low dispersion spectra.

 IUEDAC SOFTWARE AND HARDWARE UPDATES 

Recent Software Changes:

18-May  A new version of IUEFETCH was implemented which 
        properly reads SAV files containing vectors with 
        more than 32,767 points. 

23-May  New experimental routines now available:
         MOLG - A non-menu-driven merged log search routine 
                which allows searches based on a list of camera 
                and image numbers.
         GETSPEC - A binary table FITS reader particularly suited 
                   for reading output files from GEX, MGEX, 
                   and BOXCAR routines.
         LISTCORR - Lists possible corrections needed for 
                    particular IUESIPS files based on entries 
                    found in record 0. 

23-May  New versions of PLATFORM and PLOTPRINT were implemented 
        to allow Mac and PC IDL users to produce postscript 
        plot files even though a printer may not be defined. 
        A new version of IUELIB was also implemented to properly 
        format plot files on PC's. 

25-May  All the currently available final archive MXLO files 
        for SWP & LWP low dispersion standard star spectra 
        have been added to the online IUEDAC standard star 
        library in !iuer.stds. New versions of the routines 
        RDSTDS & STDSFILE have been added to the experimental 
        library to assist users in accessing the new files.

25-May  A new routine called FES2V has been added to the 
        experimental library for converting FES counts to 
        visual magnitudes.

08-Jun  The IUE merged observing log has been updated. 
        Goddard entries through May 5th are now included.

 ANONYMOUS FTP UPDATE

The IUE Merged Observing Log has been updated; it now includes 
Goddard entries through 5 May 1995.  It may be retrieved 
via anonymous FTP:

Node    Version    Location                 File

iue     vms        [anonymous.iuedac]      database.bck

 IUE IMAGE PROCESSING NEWS - NEWSIPS PROCESSING REQUESTS

As many of you know, you are welcome to request 
specific images that you need for your research. 
They will be processed through NEWSIPS 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 quickly.

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 IUEDAC World Wide Web 
homepage listed at the beginning of this newsletter.  If 
you perform a search of the Merged Log, you have the option 
to request NEWSIPS processing.  Or you can go directly to 
the URL 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                              (use 5 digit numbers)
ENDOFLIST

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. 

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. 
Some images may be listed as already processed; an 
asterisk indicates ones that are available from NDADS. 

If you requested processing, the report will then list 
the images that have been queued for priority processing.  
If you requested a report, it will list the images that 
are queued for processing (both priority and non-priority). 

Sometimes images will be listed as not ready for processing.  
This may be because some information is still needed to 
properly process the image.  Or the image may fall in a 
data set (such as high dispersion, or LWR images)
that we can't process yet.  

Finally VILSPA images will be listed.  We are generally 
not processing VILSPA images, due to the increased workload 
that would be required. 

If you have requested processing, you will receive another 
e-mail message when your priority processed images have 
been completed. 

If we are unable to process an image when you submit your 
request, you will need to re-request it at a later date.  
It is not possible for us to retain and resubmit all the 
requests we have received.

Feel free to contact Cathy Imhoff (imhoff@iuegtc.gsfc.nasa.gov, 
or 301-794-1470) for further information about your requests.

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.  We are now 
processing Goddard SWP low dispersion images taken after 1990.

If you are not familiar with the procedures for retrieving 
data from NDADS, please contact the IUEDAC staff for help.
