All years analysis

This Table contains results of our analysis of an "interior" accuracy of CCD positional Numbered Minor Planets observations carried out in indication month of current year. The observatories taken into consideration are given with their MPC codes and instrumental equipment. A number of considered Numbered Minor Planets and their processed positions is given together with a mean error of a single observation for RA and DEC. Only one night observations were used for getting these errors.

A visitor may click required MPC code number (blue color) and see the first 100 Kb information as to detailed test of CCD positions made with this MPC code and sent to the MPC Database. These information tables show the (O-C) values for each observation.

If you find any inaccurate recording, please, send us a letter for correction.

This Table contains results of our analysis of an "exterior" accuracy of CCD positional Numbered Minor Planets observations carried out in indication month of current year. The observatories taken into consideration are given with their MPC codes and instrumental equipment. A number of considered Numbered Minor Planets and their processed positions is given together with a mean error of a single observation for RA and DEC. Several close night observations were used for getting these errors. A visitor may click required MPC code number (blue color) and see the first 100 Kb information as to detailed test of CCD positions made with this MPC code and sent to the MPC Database. These information tables show the (O-C) values for each observation.

If you find any inaccurate recording, please, send us a letter for correction.
