# The
INTEGRAL Guest Observer Facility at GSFC

The mission of the INTEGRAL Guest Observer Facility at NASA/GSFC was to provide support for
US-based scientists wishing to utilize INTEGRAL data in the research.

A mirror of the INTEGRAL public data
archive at the ISDC in
Versoix, Switzerland, is available through the HEASARC at NASA/GSFC. The data is
accessible at either site via the HEASARC's W3Browse facility. The INTEGRAL archive at the
HEASARC is maintained by the INTEGRAL GOF and HEASARC staffs.

The current INTEGRAL OSA software releases from the ISDC are also available from
this website as
binaries for the Linux and Mac OS X operatings systems as well as source code.
In addition to the ESA INTEGRAL help desk, e-mail and
telephone support to U.S. participants is available through the GOF.

The INTEGRAL Guest
Observer Program is managed by ESA with data distribution and user support provided by the
INTEGRAL Science Data Center (ISDC).
