ABSOLUTE VISUAL MAGNITUDE
* IAU-adopted absolute V magnitude (H)
(MAGNITUDE) |
SLOPE PARAMETER * IAU-adopted slope parameter (G) | SLOPE PARAMETER ORIGIN FLAG * Those slope parameters that were determined by fitting the IAU-adopted phase function to data are given an origin code letter of 'f' (for 'fitted'); all others are given a code letter of 'a' (for 'assumed'). | MPC REFERENCE * Minor Planet Circular (MPC) or Minor Planet Orbit Supplement (MPO) reference |
