How do I get access to the ROSAT archive?

First, you should find out what you want to retrieve -- see question #2.
Then, you can access data
1. via ftp:
  There are 3 ftp sites (GSFC, MPE and Leicester) which serve public ROSAT data. At GSFC, the ROSAT data archive directory structure is
  rosat/<inst>/processed_data/<group>/<sequence_id>
  where
  <sequence_id> is of the form r<detector-code><ROR><obs-code><extensions>
  (for example, rp900176a01; see http://heasarc.gsfc.nasa.gov/docs/rosat/rdf_seq_names.html for more information on sequence naming conventions)
  <group> is the 1st digit of the ROR number x 100000 (if the sequence_id = rp900176a01, the group is 900000)
  <inst> is either pspc or hri
  So, to retrieve the sequence rp900176a01 from the GSFC archive, do the following:
```
               your-machine% ftp legacy.gsfc.nasa.gov
               username: anonymous
               password: your_name@
               ftp> cd rosat/data/pspc/processed_data/900000/rp900176a01
               ftp> bin
               ftp> hash
               ftp> mget *.*
               ftp> quit  
               
```
  You can also use your web browser to access any dataset via anonymous ftp too; for example, pointing your browser at the URL ftp://legacy.gsfc.nasa.gov/rosat/data/pspc/processed_data/900000/rp900176a01 will point you to the archive data directory containing the rp900176a01 data files; to download, just click.
