cds-question@unistra.frglobular-star-clustersstellar-evolutionary-modelsphotometryThe intrinsic uncertainty (due to statistical effects) affecting the integrated colours and mass-to-light ratios as a function of the cluster's integrated visual magnitude (M_V^tot^_) is studied. We investigate the case of metal-poor, single-burst stellar populations with age from a few million years to a likely upper value for the Galactic globular cluster ages. Monte Carlo techniques are used for randomly generating stars distributed according to the cluster's mass function. Integrated colours and mass-to-light ratios in different photometric bands are presented as a function of age for different assumptions on the cluster total V magnitude and they are checked for good agreement with the observational values of low-metallicity Galactic clusters.2007A&A...462..107Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/462/107CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/462/107https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/462/107http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/462/107https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/462/107https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/462/107http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/462/107GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/462/107/table2Integrated colours in the standard photometric systemalphaModel alpha value (IMF exponent) (1)stat.paramfloatrecnoRecord number assigned by the VizieR team.
