Component Overview

A description of the Cone Search and Upload List area.

Component Features and Functionality

Below you can find a description of the features and capabilities of this component.

You do not need to specify a coordinate or object name to resolve into coordinates. You can use the search form to conduct a search based only on other search parameters, or even no parameters at all!

Search By A Single Object Name To Resolve Into Coordinates

One option is to enter an object name into the Target Search box.  The form will then attempt to resolve this object name into a coordinate using the MAST name resolver service.  The resolver service looks up the object's name using a number of interfaces, including Simbad, NED, and several databases at MAST.  These are the central coordinates used to include a spatial cone search, along with any other query constraints you include in the rest of the search form.

Search By A Single Object's Coordinates

Another option is to enter the coordinates of the desired cone search into the Target Search box.  The form will then attempt to parse the coordinates, which can be specified in decimal degrees or sexagesimal format (Right Ascension in HH:MM:SS, Declination in DD:MM:SS).  Right Ascension values outside the bounds of 0 <= R.A. <= 360. will be wrapped to fit within these bounds.  Declination values outside the bounds of -90.0 <= Dec. <= 90.0 are defined as invalid.

Upload A List Of Object Names To Resolve, Coordinates, or Dataset IDs

Another option is to upload a list of object names to resolve, coordinates, or dataset IDs.  NEED TO GO THROUGH A LOT MORE HERE.

Specifying The Size Of Your Cone Search

Regardless of how you request a position on the sky (through a single, resolvable object name, a single, parsable coordinate, an uploaded list of resolvable object names, or an uploaded list of coordinates) you can control the size of the cone search by specifying a radius in either arc seconds or arcminutes.  A maximum of 30 arcminutes is allowed.  Note that if you upload a list of Dataset IDs, this component is not used, because a cone search is not conducted.  When supplying a list of Dataset IDs, a direct match on the IDs is performed instead.
