Folks:

Please forgive me if you get this message more than once.  I want to 
make sure this gets out to everybody who needs to know.

The STEREO mission uses a particular kind of ephemeris file known as 
SPICE for the orbit and attitude information, and there are routines in 
the SolarSoft "$SSW/stereo/gen" tree for handling the files.  The 
upcoming Solar Orbiter and Solar Probe Plus missions will also use the 
SPICE ephemeris system, so the STEREO software for handling SPICE files 
has been migrated to a separate package called "SunSPICE".  This should 
be transparent to most users, but people who are using SolarSoft under 
Windows will need to install the SunSPICE package on their machines.  
This is explained on this website:

Please let me know if you have any problems.
