4. Do you want to change your current query settings?


(e.g. 'Cyg X-1' or '12 00 00, 4 12 6')
Use semicolons (;) to separate multiple object names or coordinate pairs (e.g. 'Cyg X-2; 12.235, 15.345').
Default uses the optimum radius for each catalog searched.

Not all tables have observation dates/times. For those that do, the time portion of the date is optional.
Times are always in UTC. Separate multiple dates/ranges with semicolons (;). Range operator is '..'
(e.g. '1992-12-31; 48980.5; 1995-01-15 12:00:00; 1997-03-20 .. 2000-10-18').
