This directory contains a variety of SPICE kernels that defined the           
spacecraft, instrument, and target (Borrelly) geometry. The official          
SPICE archive products are maintained by the NAIF node of the PDS. These      
files are reproduced here for user convenience.

DS1_BORRELLY_V01.TPC    Planetary constants kernel for Borrelly.              
DS1_PEPE_V20.TI         PEPE instrument frame kernel (gives instrument        
                        look directions, elevation and azimuth bins,          
                        and various calibration parameters (geom factors,     
                        mass range/resolution, etc.)                          
DS1_SCLKSCET_00071.TSC  DS1 spacecraft clock kernel (used to convert          
                        clock values into SCET).                              
SP19P_AUT118.XSP        Ephemeris kernel.
