SIMPS MEAN ALBEDO * Mean derived geometric albedo on the H,G system from the Supplemental IRAS Minor Planet Survey (SIMPS).	SIMPS MEAN ALBEDO UNC * 1-sigma uncertainty in the mean derived geometric albedo from the Supplemental IRAS Minor Planet Survey (SIMPS), due solely to the precision of the IRAS flux data.	SIMPS MEAN DIAMETER * Mean diameter from the Supplemental IRAS Minor Planet Survey (SIMPS), computed from H and SIMPS_MEAN_ALBEDO (KILOMETERS)	SIMPS MEAN DIAMETER UNC * 1-sigma uncertainty in the mean diameter from the Supplemental IRAS Minor Planet Survey (SIMPS), due solely to the precision of the IRAS flux data.	SIMPS PLC * Probability of lightcurve variation, estimated in the Supplemental IRAS Minor Planet Survey (SIMPS). This quantity is used as a measure of the probability that a lightcurve effect is present in the data. Values are constrained to be between 0.10 and 1.00. Less than significant variation is assigned a value of 0.10.
