RA in hour angle, decimal or sexagesimal value

Dec in degree, decimal or sexagesimal value
Enter Dec in degree (decimal or sexagesimal in degree:minute:second format) to filter using a J2000 FK5 position. For example, "19.82619" or "19:49:34.3".
Radius in degree, decimal value
Radius to filter using a J2000 FK5 position.
Object
A substring match will be used for the Object input. The FITS OBJECT values are searched. For example, the input "13936" would match a FITS data with "HD13936" in the OBJECT field.
Observer
A substring match will be used for the Observer input. The FITS OBSERVER values are searched. For example, the input "joseph" would match FITS data with "Joseph, Rothberg, Bendo" in the OBSERVER field.
