NOTES
A) The ephemeris used in this prediction is that generated for Pluto with JPL's Horizon's Ephemeris service (corrected for Light Travel time). Ephemeris Files used included PLU013.
B) Results for P468 are tabulated as offsets from the position given by UCAC2 catalog. Results for Pluto (if any) are tabulated as offsets from the unmodified JPL Horizon's ephemeris. Strip scan reduction includes simultaneous least-squares point spread fitting to Pluto and Charon as well as P468, and uses the UCAC2 catalog for astrometric calibration.
