CHANGES TO THE ROSAT PUBLIC ARCHIVE TABLE 
*****************************************
A revision to the naming convention for follow-up observations required
us to make some changes to the ROSAT Public Archive Table (which is
available via anonymous ftp from legacy and also available as the
ROSPUBLIC database under the HEASARC BROWSE interface).  We've revised
this table to incorporate the new naming convention and have added some
useful information which previous versions of the table lacked.  For
every data set which has been released to the ROSAT Public Archive, the
new data table contains the following information:


SEQ ID  = sequence id
INST    = instrument (PSPC or HRI)
F       = boron filter used (Y/N)
SITE    = data processing site
EXPTIME = exposure time in seconds
REQT    = requested time in ksec
RA      = RA in J2000
DEC     = Dec in J2000
START   = start of observation (yymmdd)
END     = end of observation (yymmdd)
DISTR   = distribution date (yymmdd)
PUBLIC  = public date (yymmdd)
TARGET  = name of target
PI      = last name of principal investigator 
F       = first initial of principal investigator
ROR	= 6 digit ROR number
INDEX   = follow-on index (ie A00)
C	= subject category
R	= revision
TITLE 	= proposal title

This data table is available from anonymous FTP from
legacy.gsfc.nasa.gov in the directory rosat/doc/archive and comes in 2
flavors:
	rosarchive_yymm.pos = sorted by position
	rosarchive_yymm.seq = sorted by sequence ID
where yymm is the year/month of the last update.

Users of the HEASARC BROWSE interface can access this table by browsing
the ROSPUBLIC data base.  

BROWSE users should also note that information on ROSAT dataset
distribution will be available through the ROSDISTRIB data table.

The updated ROSPUBLIC and ROSDISTRIB data tables will be available
through BROWSE on MONDAY, AUGUST 8, 1994.


WFC POINTED IMAGES AVAILABLE 
****************************
Public EUV images obtained by the Wide Field Camera on ROSAT are now
available via anonymous ftp from legacy.gsfc.nasa.gov.  The images are
located in the directory
	rosat/data/wfc
and are in FITS format.  We have found that some of the FITS headers
have the WCS keyword CTYPE2 incorrectly labelled as CTYPE1, so users
should be advised.  We are presently working on correcting this
problem.

BROWSE users can consult the data table WFCPOINT to determine which
images are (or will be) available.


PROPOSAL ABSTRACTS NOW AVAILABLE FROM ROSAO DATA TABLE IN BROWSE
****************************************************************
Proposal abstracts have been added as a data product to the ROSAO data
table in BROWSE.  Users can now obtain as an ASCII text file the
abstract of any proposal listed using the xp/abs command.
