Globular clusters luminosity function

The original HST magnitude is given, then the corresponding bolometric magnitude and the converted luminosity function. The vertical scale of the LF is arbitrary (it is the scale used on the figure).

The conversion between the HST and bolometric magnitudes uses a spline fit of the theoretical models of Baraffe et al. (1997A&A...327.1054B), for the appropriate metallicities. The name of the cluster and of the observational paper main authors are given as a header, followed by the magnitudes description and the data.
