Reiner, Note that the slope parameter G is 0.15. This is a default value that is often used when a least-squares routine fails to converge to a combined slope...
I think it is worth mentioning that the Minor Planet Center is a collector of *astrometric* information. The magnitudes given by MPC should only be taken as...
... Not necessarily. Some astrometric observers do not report apparent magnitudes. In this case, 20 of the 146 observations in the mpn.arc database are blank...
