cds-question@unistra.fropen-star-clustersvisible-astronomynarrow-band-photometryThe two clusters NGC 2451 A and B will be examined on the basis of Geneva multicolour photometric measurements. P and Q are the sum of the individual weights divided by 3 for the colours and the V magnitude respectively.
