ANALYSIS OF MAP ASTEROIDS WITH MODIFICATIONS OF H MAGNITUDE BY THE MPC ON JANUARY 31.2010
                   
Since September 2008, the Minor Planet Center changed a total of 53922 numbered asteroids, up to January 31,2010
The MAP has 520 asteroids in its database. Among them, 141 objects already have their H magnitude concerned by the recent MPC corrections.
Total of resulting new differences of H magnitude ( MAP - MPC ) by tenths of magnitude :
All Asteroids Only asteroids observed during at least 3 oppositions
New H MPC = H MAP 13 9,15 % New H MPC = H MAP 5 20,00 %
Difference of 0.1 mag 34 23,94 % Difference of 0.1 mag 7 28,00 %
Difference of 0.2 mag 21 14,79 % Difference of 0.2 mag 1 4,00 %
Difference of 0.3 mag 24 16,90 % Difference of 0.3 mag 4 16,00 %
Difference of 0.4 mag 13 9,15 % Difference of 0.4 mag 2 8,00 %
Difference of 0.5 mag 12 8,45 % Difference of 0.5 mag 3 12,00 %
Difference of 0.6 mag 13 9,15 % Difference of 0.6 mag 2 8,00 %
Difference of 0.7 mag 7 4,93 % Difference of 0.7 mag
Difference of 0.8 mag 2 1,41 % Difference of 0.8 mag
Difference of 0.9 mag 2 1,41 % Difference of 0.9 mag
141 24
For the asteroids seen at least during 3 oppositions, the new H MPC is similar to about 48% ( 0.0 to 0.1 mag of difference ) with the H MAP
The causes of the differences may be : erroneous observed magnitudes, R MPC magnitudes marked V, impact of high light variability
Nevertheless, only 26 averaged differences of H magnitude increased after the MPC modifications ( 18.4% of the 141 H modifications by the MPC )
TABLE OF THE MAP ASTEROIDS WITH A H MAGNITUDE CHANGED BY THE MPC SINCE AUGUST 2008
Legends of "Div.(N)" : M1, M2, ... = MAP object, with the total of observed oppositions by the MAP
Mc = old MAP object, no longer followed by the MAP, due to a lack of real discrepancy of H magnitude
Mp = MAP object for which results were published in the Minor Planet Bulletin 2007
NM.. = Asteroid seen by MAP observers since the MAP birth, with a H magnitude changed recently by the MPC
Legends of "# H MAP" : B/x.x = H magnitude x.x magnitude brighter than the official one
F/x.x = H magnitude x.x magnitude fainter than the official one
Legend of columns "# H" = = Difference between the H MPC before September 2008 and the H MPC at the date of the update of this file
Legend of column "# H MAP N" = Modified difference of the H MAP After the last modification of H magnitude by the MPC
