Abstract:
Galactic open clusters provide an abundant sample of stellar
aggregates of various sizes, ages and metal abundances, apt to
constitute a template for comparison with star systems in other
galaxies. In this paper we present and discuss a standard methodology
to synthesize U,B,V fluxes and colours, and apply it to a set of 138
open clusters. Results are compared with previous ones available in
the literature. We were able to calibrate a mass-luminosity relation
by which we evaluated the mass of ∼ 400 open clusters, leading to a
well defined present-day mass function. The number-complete sample of
galactic open clusters presented in Battinelli & Capuzzo-Dolcetta
(1992AJ....103.1596B 1992AJ....103.1596B) is enlarged of a 15%.

Symbol c stands for clusters in the "complete" sample and
symbol : stands for uncertain values.
Hog 17 is included in the sample due to BCD determination based on a
higher number of members (41).
