Description:
The 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.
For a description of the Geneva photometric system, see e.g.
GCPD/13
