Measured OC (top) and SC (bottom) albedo values from Goldstone (from Table 4) as well as S. J. Ostro et al.’s (1992) OC and SC albedo values (black stars). At comparable longitudes, our values agree well with S. J. Ostro et al.’s (1992), except for epochs at west longitude ∼87°, where S. J. Ostro et al.’s (1992) SC albedo appears larger than ours, but they still agree within the uncertainty, given that the uncertainty of S. J. Ostro et al.’s (1992) values is around 35%, the average of their published range of uncertainties (20%–50%). The error bars on our values are taken to be the total uncertainty calculated in Section 4. The color bar on the right indicates the dates of our observations in YYMMDD. The x-axis is the subradar point west longitude.
