Foreword
N. E. White
HEASARC
The first CD-ROM of
data from the ROSAT mission was
released at the AAS meeting held in
Crystal City, Virginia and is
available from the HEASARC. It
contains images from the first six
months of pointed observations and
provides a complete overview of
each observation. It can be used
for source detection, or simply to
get a quick overview of each
observation. The CD-ROM and updates
to the various ways the HEASARC
data can be accessed are described
in this issue of Legacy. The
exponential growth in the use of
the World Wide Web has caught our
attention and we are making many
services available through this
medium, including the HEASARC data
browser. A new tool, SkyView, is
described and will provide remote
access to all-sky survey data,
including the HEAO-1 A2 X-ray
survey. The HEASARC data
restoration effort is proceeding
and the status of the COS B, SAS 2,
Vela 5B and Ariel V all-sky monitor
data are reported. There has been a
major effort to begin restoration
of data tapes from the HEAO-1 A2
and OSO-8 missions, that were in
the basement of building 2 at GSFC.
The first stage of simply
cataloging and moving the tapes to
a more modern medium is described.
A new FITS working group has been
established to coordinate and give
advice on how to structure FITS
files and conventions for FITS
keywords. These standards are
essential if the restored data is
to be made available in a
multi-mission form.
