Foreword
N. E. White
HEASARC
The ASCA archival data
is now flowing to the HEASARC and
the first data were made available
on 15 November 1994. These data are
accessible through the standard
HEASARC online services, using ftp,
gopher, the WWW and remote login
Browse user interfaces. The HEASARC
has also made available the first
two ROSAT catalogs, from the
pointed phase, with over 45,000
sources. One, WGACAT, was generated
by the HEASARC, in collaboration
with the ESIS project in Europe.
The other, ROSATSRC, was made by
the ROSAT project. The
identification of these sources
will provide a major new boost to
our understanding of the X-ray sky.
The data restoration effort is
moving along rapidly, and in this
issue new data available from the
HEAO 1 mission are announced. The
sky survey map data from the A2
experiment are now available and
are featured on the cover. Also the
UCSD group has converted the
spectral data products from the
hard X-ray experiment to FITS
format and these are now available
through the HEASARC. The
calibration of the BBXRT experiment
on the Astro 1 mission is
explained. The SkyView facility now
provides instant access to many sky
surveys, including the Digitized
Southern sky survey. It is proving
an extremely popular and useful
tool to professional and amature
astronomers alike.
