... For reliable estimation of the accuracy of asteroid CCD observations we usually consider from ten or more various NUMBERED MINOR PLANETS (NMPs) observed during several nigths per month (more then 50 positions). ... They can be considered as an indicator of accuracy of the CCD positional observations with given MPC code. ... For any NUMBERED minor planet the (O-C) values must be zero if the errors of observations and the errors of its theory are absent. ...
The Mass Function of Dark Halos in Sup erclusters and Voids E. P. Kurbatov1 1 ,* Institute of Astronomy of the Russian Academy of Sciences A mo dification of the PressSchechter theory allowing for presence of a background large-scale structure (LSS) a sup ercluster or a void is prop osed.
