Function nedUrl( sourceId )

Description:
Maps a source identifier to the URL of its NED web page. NED is the NASA/IPAC Extragalactic Database.

The string "http://ned.ipac.caltech.edu/byname?objname=" is prepended to the given id string, and any necessary character escaping is applied. No attempt is made to validate whether the supplied string is a real source identifier, so there is no guarantee that the returned URL will contain actual results.

Parameters:
sourceId (String)
free text assumed to represent a source identifier known by NED
Return Value (String):
URL of the NED web page describing the identified source
Example:
nedUrl("NGC 3952") = "http://ned.ipac.caltech.edu/byname?objname=NGC%203952"
Signature:
String nedUrl(String)
