gnomcursor
This IDL facility provides a point-and-click interface for finding
the astronomical location, value and pixel index of the pixels nearest
to the pointed position on a gnomonic projection of a HEALPix map.

QUALIFIERS
see mollcursor
DESCRIPTION
gnomcursor should be called immediately after gnomview. It gives the longitude,
latitude, map value and pixel number
corresponding to the cursor position in the window containing the map generated
by gnomview. For more details, or in case
of problems under Mac OS X, see mollcursor.

EXAMPLE:
After gnomview has read in a map and generated
its gnomonic projection, gnomcursor is run to determine the
position and flux of bright synchrotron sources, for example.
