M103. Compared to the estimates of Loktin et al., E(B-V) is increased from 0.382 mag to 0.39 mag. * 47. M 45. There are 9 bright (V<5.5) stars located in the cluster core (dr<=r_core), but only 4 of them have P_kin & P_ph >=61: V B-V P_ki P_ph +2.870 -0.062 94.30 100.00 +3.622 -0.070 49.18 100.00 +3.706 -0.092 89.75 100.00 +3.870 -0.055 61.04 100.00 +4.164 -0.047 90.17 004.39 +4.293 -0.091 51.56 100.00 +5.048 -0.079 11.39 100.00 +5.440 -0.065 40.95 100.00 +5.447 -0.038 88.80 100.00 It is possible that the mean errors of proper motions and photometric data used for computing the probabilities are underestimated in the original catalogues. Otherwise, we should assume an internal spread of the kinematical and photometric parameters in the cluster. * 74. M 42. Trapezium. The cluster is younger than the age derived from the Turn-off point. It is a very difficult case for the applied member selection pipeline: From six bright (V<6.7) Trapezium stars only one has both probabilities P_kin & P_ph >=61. V B-V P_ki P_ph 5.018 -0.036 04.12 00.27 5.068 -0.023 19.66 00.56 5.802 -0.239 00.79 94.84 6.206 -0.123 69.38 100.00 6.538 -0.020 57.78 02.73 6.710 +0.070 57.81 00.66 * 82. M 37. The Turn-off point at V = 12.5 (given in literature) cannot be observed with the ASCC-2.5 data. A few most probable and bright members yield a too young age (log t = 8.29) for the cluster. Therefore, the age estimate of log t = 8.54 by Loktin et al. and the corresponding isochrone are accepted. * 201. M 44. Due to proper motion errors underestimated in the original catalogue and/or intermal motion, a complete selection of cluster members is difficult. * 212. M 67. The Turn-off point is fainter than the limiting magnitude of the ASCC-2.5. There are only a few brighter blue stragglers which are the most probable cluster members. The age estimate by Loktin (log t = 9.41) and the corresponding isochrone are adopted. * 428. M 8. Compared to the estimates of Loktin et al., E(B-V) is decreased from 0.32 mag to 0.30 mag. * 440. M 24. The CMD is complex. The distance (d = 2880 pc) from the Lynga catalogue is accepted. We derived E(B-V) = 0.50 mag. * 441. M 16. The reddening is very variable. Compared to the estimates of Loktin et al., E(B-V) is decreased from 0.76 mag to 0.70 mag. * 449. M 25. Compared to the estimates of Loktin et al., E(B-V) is decreased from 0.476 mag to 0.45 mag. * 488. M 29. The reddening is very variable. Compared to the estimates of Loktin et al., E(B-V) is increased from 0.74 mag to 0.98 mag.
