Abstract
We have used HST and ground-based photometry to determine total $V$-band
magnitudes and mass-to-light ratios of more than 150 Galactic globular
clusters. We do this by summing up the magnitudes of their individual member
stars, using color-magnitude information, Gaia DR2 proper motions and radial
velocities to distinguish cluster stars from background stars. Our new
magnitudes confirm literature estimates for bright clusters with V<8, but can
deviate by up to two magnitudes from literature values for fainter clusters.
They lead to absolute mass-to-light ratios that are confined to the narrow
range 1.4
