EXOSAT ivo://nasa.heasarc/exomaster NASA/GSFC HEASARC HEASARC 2026-04-10 NASA/GSFC HEASARC help desk heasarc-vo at athena.gsfc.nasa.gov Observation The EXOMASTER database contains the EXOSAT observation log. This is a complete list of all EXOSAT observations, observing modes, and principal investigators. The log can be used to find out which targets were observed by EXOSAT, who observed them and the observation configuration. In addition this database can also be used to check the availability of the FOT (Final Observation Tape) files (the original raw data files) and their reformatted FITS files. This database table was originally created in September/October, 1997. The HEASARC revised this database table in August, 2006, in order to fix the equatorial coordinates (which were in the wrong equinox) and to rename or convert some of the time-related fields to better conform with current HEASARC practices.
