Probably the most common use of the ROSAT Results Archive will be via electronic access (WWW, ftp, etc.) since this source list, unlike the Einstein 2E catalog, will not be complete until some undetermined date in the future. Thus we are not making any sort of 'hard copy' (e.g. cdrom) at this time. All the documents describing the archive, the different catalogs, and the current ``filling factor" of the archive are provided online as well.
The primary documents for the RRA are listed here.
