Recent data restoration additions to the HEASARC archive

HEASARC has restored data from many of the past X-ray astronomy missions. The most recent additions to the archive are data collected with OSO-8 GSFC Cosmic X-ray Spectroscopy Experiment (GCXSE), HEAO-1 A-2 experiment, Copernicus (OAO-3) University College of London Experiment UCLXE) and the EXOSAT low energy detectors. These data are in FITS format and they can be manipulated with generic tools that work on FITS files. Mission specific software is also available to extract high level products appropriate to the data from each mission as lightcurves, spectra or images. We present the content of the final archive for these missions, how the data can be retrieved and used. Analysis for specific sources from each of the data sets are presented to highlight the mission capability and the potential of the data.
