Notes. The parameters shown are the mean (and standard deviation) for the (N) members found also including the apparent angular size (θ) and estimated distance (d) with one sigma confidence interval. Radial velocity is included when available and is computed with NVrad members. The name follows the numeration of CG19. The full list can be found online at the CDS.
