Meeting to discuss possible Percy enhancements - 06/04/01

Attendees:
Rusty Whitman
Scott Stallcup

Percy uses custom code to support graphics devices/formats.  Currently the 
only file format supported is postscript.  Support for additional devices
can be added and should be similar in effort to what was required to add
postscript support.

JPL maintains the SpiceLib package.  It is available in both C and Fortran
versions.  Percy uses the Fortran version of Spicelib with STScI enhancements.
Ephemeris files are provided by JPL [Andy L. says new version need only be 
obtained every few years].

Binary versions of the Percy application are distributed if requested.

At one point there was some interest in converting Percy to run as a server
but after investigation it was found to require massive changes to the
application.

Percy has some limitations on the number of ephemeris files that can be opened at
once. [this should not be a problem for moving target support since only one or two
objects are usually involved]
