The number of Browse table requests to our database increased by 12% in 2001 compared
to 2000 (there were 225,071 total queries involving 682,054 table requests in 2001).
The Browse Batch mode was the most popular (68% of the total queries), but likely many
of these queries were from a relatively small number of users; next came the more advanced
Cone & Parameter searches (20% of the total queries), then basic searches (11% of the total
queries), and finally cross-correlations (1% of the total queries).
The most popular Browse tables in 2001 were from the ROSAT mission,followed
by tables from the ASCA, RXTE, Chandra and BeppoSAX missions (see below);
the tables requested were very diverse, i.e., the top 20 tables comprised only 44%
of the total requested tables.
