NOTES
A) The separation between the center line and each of the limb lines is an estimated Pluto radius. (1150 km)
B) 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 PLU006.
C) 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.
D) Results for P384.2 are tabulated as offsets from the position given in prediction version P384.2-U2.0-1.0. 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 P384.2, and uses the UCAC2 catalog for astrometric calibration.
