RASSMASTER - ROSAT All-Sky Survey Archival Data
For each observation listed in this database table, the instrument used, processing site, and coordinates of the field center are given, as well as the ROSAT observation request number (ROR), actual exposure time, date the observation took place, and more.
For details about the ROSAT instruments, consult the ROSAT Mission Description (NASA Research Announcement for ROSAT, Appendix F and its addendum) and the ROSAT GSFC GOF website at http://heasarc.gsfc.nasa.gov/docs/rosat/rosgof.html for more information.

The sequence identification number (e.g. RS123456N00), where the prefix is 'RS' for a PSPC All-Sky Survey scanning mode observation. The next 6 characters are the ROSAT observation request sequence number or ROR, while the following 3 characters after the ROR number are the follow-on suffix. A complete pointing at a given ROSAT target comprises all the datasets having the same prefix and ROR numbers.
The instrument used for the observation (PSPC, HRI).
Flag to indicate whether a filter was used.
The site where this data set was processed (GSFC, MPE).
The exposure of the pointing, in seconds. This entry represents the maximum amount of exposure time obtained as measured in the merged exposure map (the file ending in _mex.fits).
FITS file format version.
The right ascension of the target.
The declination of the target.
The galactic longitude of the target, calculated from the right ascension and declination.
The galactic latitude of the target, calculated from the right ascension and declination.
Date Observation Began
Date Observation Ended
The date that the data were distributed to the archive.
The date that the data were made public.
The ROSAT observation request (ROR) sequence number.
The revision number of the processing system used to generate the data products.
The generic title of the pointing.
