Watchlists

Create New Watchlist

A Watchlist is composed of a set of locations in the sky, together with an association radius in arcseconds. These locations are presumably coordinates of sources of specific interest to you. Use a Watchlist to be alerted of transient events found in association with any of these sources. Your Watchlists will appear in the My Watchlists of the Watchlists index.

A watchlist is generated from a set of points in the sky, together with an association radius. Each transient falling within an association radius of a watchlist source is flagged as matched against that watchlist.
