A.8.5 Multiple Cone Search Window

Multiple cone search window

Multiple cone search window

The multiple cone search window can be opened using the Multicone button () in the Control Window's toolbar, or its VO or Joins menus. It allows you to select one of a number of external web services which provide remote catalogue queries, and execute a query for each row of an input table. This effectively allows you to perform a positional crossmatch between a local table and a remote one.

The window consists of a Registry Query Panel at the top, and a Multiple Positional Search Panel below.

The search panel includes a Verbosity selector as well as the normal features: this allows you to choose options for how many columns will appear in the output table, from 1 (minimum) to 3 (maximum). Some services will take notice of this parameter and return narrower or wider tables respectively, and others will ignore it.
