1. Enter any constraints on the query below. [ Help on constraint syntax ]

(What about wildcards, spaces, and case sensitivity?)

2. To change the fields that are returned, select the box in the "View" column beside each field desired.

3. To sort the results by any field, select one box in the "Sort" column beside the field to sort on.

(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').
