**********
ISM SERVER
**********

The EUVE Science Archive is announcing a new service which allows users
to calculate interstellar medium transmission remotely, via electronic
mail.  The ISM server, installed under the "archive" e-mail address,
can feed the input variables sent within an e-mail message to the ISM
executable located in the archive.  The server then will automatically
return output values to the sender in an electronic mail message.  The
ISM model employed is that of Rumph, T., Bowyer, S., and Vennes, S.,
1993, ApJ submitted (available from the Center for EUV Astrophysics in
preprint form by request to editorial@cea.berkeley.edu or the lead
author; toddr@cea.berkeley.edu)

The mailserver uses the same C routines as those which reside in the 
archive ism directory, and which are available for copying through
the mailserver or by anonymous FTP.

To use the ISM server send email to archive@cea.berkeley.edu.

The first line of the text of the message should be in the following
format:  the word "ism" (omit quotes) followed by the hydrogen column
density (in units number/cm**2), a space, the neutral helium to neutral
hydrogen number density ratio (HeI/HI), a space, the once ionized He to
neutral hydrogen number density ratio (HeII/He) and a carriage return.

The succeeding lines should contain x,y pairs corresponding to
wavelength in Angstroms, and unattenuated flux, separated by a spaces.

The output file, returned to the user via email, will have two columns,
wavelength and the flux*ism_transmission.


For example, the following message will be interpreted by the
mailserver program as a request for an ISM calculation, using a H
column of 1.0e18, with HeI/HI=0.1 and HeII/HI=0.01, for the wavelengths
and fluxes on the lines following the "ism" keyword :-

300.000000 0.567427

Note that the fluxes can be in any units.  (Submitting 1.0 as the flux
for a given wavelength yields, of course, the transmission factor,
which, when multiplied by a flux in arbitrary units yields the
ISM-attenuated flux.)


This facility is a prototype of a service which is planned for future 
implementation, whereby the user can submit input data for a variety 
of on-line programs using electronic mail. 

WARNING
-------

The ism routine should not be treated as a black box.  While
it has been extensively tested, The EUVE Archive does not hold
responsibility for any errors or for any consequences of errors 
which might remain.


NEW EGO RELEASES

***********************************
Announcement of AU Mic data release 
***********************************

The entire AU Mic data set including flare episode obtained last July
2-4, 1992 will be released on August 2, 1993.  The data will be
distributed on 8mm tape in the standard EUVE Guest Observer format
including nominally reduced 1-d spectra, all raw data (photon events
and engineering telemetry), reference data, analysis software, and
QPOE files.  The data is NOT proprietary and may be used for analysis
and publication once the data is released.   The data may be ordered
by sending a request to (Internet) "egoinfo@cea.berkeley.edu".
Technical questions regarding the analysis software should likewise be
directed to "egoinfo@cea.berkeley.edu" or phone (510)-643-5056.
Support will be provided on a best effort basis.  The data from the
upcoming AU Mic observation scheduled for July 22, 1993 will be
released at a later date. 

******************************
EUVE Cycle II NRA Availability
******************************

The EUVE Cycle II NRA is available to prospective Guest Observers in
paper and electronic formats.  Requests for hardcopies of the NRA
should be sent to:

       Fax:            (301) 286-7642

Requests are usually mailed out within 24 hours and copies are FedEx
to foreign countries.

Electronic copies for the NRA are available via anonymous ftp (File
Transfer Protocol), as follows:

	% ftp 128.32.154.12

If you have any questions or problems using the anonymous ftp please
contact the EUVE Guest Observer Center at:

	Internet:    egoinfo@cea.berkeley.edu
	Phone:       (510) 643-5056

Or, you may contact Dr. Yoji Kondo (Project Scientist) at (301) 286-6247
or Dr. Ron Oliversen (Deputy Project Scientist) at (301) 286-6290.

The EUVE proposals must be received by September 3, 1993 and should be sent to:

              Dr. Yoji Kondo
              NASA/Goddard Space Flight Center

              Building 21, Room G59
              Greenbelt, MD  20771.

An electronic submission of the target list (see the NRA for details)
is also required and should be send to:

              egoinfo@cea.Berkeley.EDU
 
The deadline is also September 3, 1993.
