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.
ASTRONOMY EDUCATION WITH IUE
Are you using IUE data to help teach astronomy at the
college level or in elementary, middle, or high school?
Do you have a successful IDEA (Initiative to Develop
Education through Astronomy) proposal using IUE data?
We would like to know and also to offer our support.
We would also like to help advertise the availability
of IUE-related teaching materials and help with distribution.
If you are working on a project or are interested in
learning about what others are doing with IUE data,
please contact Cathy Imhoff (301-794-1470, or
IUE IMAGE PROCESSING NEWS
Because IUE now has two processing systems running,
there has been some confusion about how current images
(those recently obtained with IUE) are handled. Newly
obtained images are still being processed with IUESIPS. We
plan to continue to process new data with IUESIPS
until the expected end of operations at the end of September
There have been very few changes to IUESIPS in the
last 5 years. The most recent change was an update of
the wavelength calibration at both NASA and VILPSA on
June 11, 1993. Changes prior to that date are given
in a "Chronology of Modifications to IUESIPS Output
Products: 1985-1993" in NASA IUE Newsletter No. 50.
Now that NEWSIPS processing for the Final Archive of
the SWP and LWP low dispersion data taken between
1978 and 1990 is essentially complete, the next
dataset to be processed for the Final Archive will be the SWP
low dispersion images taken between 1990 and 1995.
The calibrations for this portion of the SWP low
dispersion dataset will be available in about 2 weeks.
The calibrations for the LWP low dispersion data taken
between 1990 and 1995 will be available near the end
of April, 1995. After the 1990-1995 low dispersion data
are processed for the Final Archive, it is anticipated
that the SWP high dispersion data will be processed.
The LWR low dispersion data will require more effort
for calibration due to the need for two different ITFs
in the processing and unstable behavior of the detector
during the first year of operation. The LWR low dispersion
calibrations will be available near the end of summer, 1995.
The NEWSIPS software package was distributed in January.
The documentatio and electronic request form reside in an
anonymous FTP account on the IUE node. Due to legal requirements,
the software must be copied using a password that will
be supplied upon receipt of the request form.

IUE REFERENCE MATERIAL
IUE Image Processing Manuals
We have available copies of both the IUESIPS Image
Processing Manual (Version 2.0) and the NEWSIPS Image
Processing Manual (Version 1.0). Note that the NEWSIPS
Manual was also published as NASA IUE Newsletter
No. 53. Please contact Cathy Imhoff for copies.
IUE Atlases Available
We have two very useful IUE spectral atlases available
"IUE Ultraviolet Spectral Atlas" by C.-C. Wu et al.
1991, NASA IUE Newsletter, No. 43.
Plots IUE spectra, tabulates fluxes for MK standard
"IUE Ultraviolet Spectral Atlas of Selected Astronomical
Objects" by C.-C. Wu et al. 1992, NASA Ref. Publ.
No. 1285 Plots IUE spectra, tabulates fluxes for
planets, variable stars, galaxies, etc.
"Atlas of O-Type Spectra From 1200 A to 1900 A", NASA Ref.
Publ. 1155, by N. R. Walborn, J. Nichols-Bohlin,
and R. J. Panek
If you would like a copy or two, please contact Cathy Imhoff at
firstname.lastname@example.org or (301) 794-1470.
Note that the "IUE Ultraviolet Spectral Atlas" by C.-C. Wu et al.
1991, NASA IUE Newsletter, No. 43. can be accessed online
through the IUEDAC procedure STDSTARS.
IUEDAC SOFTWARE AND HARDWARE UPDATES
Recent Software Changes:
22-FEB The IUEDAC Users Tutorial has been revised and expanded,
and has been renamed the IUEDAC Users Guide. Copies
are now available by contacting the IUEDAC staff or
via the anonymous ftp account on IUESN1.
23-FEB An error was discovered in the version of READMX
implemented on Jan. 26th of this year which
resulted in large aperture data being extracted
from double aperture MXLO files, even when small
aperture data was requested. The problem has been
corrected in the new version.
ANONYMOUS FTP UPDATES
The sun_rdaf.tar.Z and ultrix_mipsel.tar.Z files in the
anonymous ftp account on iuesn1.gsfc.nasa.gov were
updated on the 15th of March 1995.
CHANGES NEEDED TO RUN THE IUEDAC SOFTWARE
UNDER SOLARIS 2
For those users running or who plan to run Solaris 2 on
their workstation a couple changes need to be made to
the UNIX version of the IUEDAC software package. If you
have a version of the IUEDAC IDL software obtained after
October 1994, the procedure uixplat.pro in your
./iuerdaf/iuelib/pro subdirectory is where the changes
will need to be made. The pdelete command command
should be changed from 'lpr -r ' to 'lp '. It does
not appear that the remove after printing option is
available. Similarly the printcmd should be changed
from 'lpr ' to 'lp '. Hopefully when the software was
installed, the correct print command(s) was(were) given
in platform.pro by the person installing the software.
To check what the print command is, type
at the IDL prompt. If there is a second print option, type
at the IDL prompt. Sorry for any inconvenience this may
have caused. The value of !version.arch and !version.os
are the same on SunOS and Solaris systems.
This problem has been reported to RSI.
