orthcursor
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 orthographic projection of a HEALPix map.

QUALIFIERS

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

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