Maybe this is stupid question, but I am not sure how to get the diameter of the star cluster, I assume from the RA and Dec. I googled it and tried to come with a realtion between the RA , Dec and Diameter from Andrea's proposal but couldn't figure the correct answer
This is all I find (see below please)... but I don't know the distance or the angular size, just RA and Dec from SIMBAD data base
diameter = 2p × (distance to the cluste) × (clsuter's angular size in degrees)/360°
