A watchlist is a set of points in the sky, together with a radius in arcseconds. It is assumed to be a list of "interesting" sources, so that any transient that falls within the radius of one of the sources might indicate activity of that source. Each user of the Lasair system has their own set of watchlists, and can be alerted when a ZTF transient is coincident with a watchlist source.

An "Active" watchlist is one that is run every day, so that it is up to date with the latest objects.

If you are logged in, you can create a watchlist.
