cds-question@unistra.frglobular-star-clustersphotometrymetallicityWe present the complete photometric database and the color-magnitude diagrams for 74 Galactic globular clusters observed with the HST/WFPC2 camera in the F439W and F555W bands. A detailed discussion of the various reduction steps is also presented, and of the procedures to transform instrumental magnitudes into both the HST F439W and F555W flight system and the standard Johnson B and V systems. We also describe the artificial star experiments which have been performed to derive the star count completeness in all the relevant branches of the color magnitude diagram. The entire photometric database and the completeness function will be made available on the Web immediately after the publication of the present paper.2002A&A...391..945Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/391/945CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/151 : Structure Parameters of Galactic Globular Clusters (Webbink 1985)VII/202 : Globular Clusters in the Milky Way (Harris, 1997)http://dipastro.pd.astro.it/globulars/databases/snapshot : Paper Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/391/945https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/391/945http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/391/945https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/391/945https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/391/945http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/391/945GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/391/945/table2 (Main parameters of the observed clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/391/945/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/391/945/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/391/945/table2?GETtext/xml+votable180.050000true6.023625-72.08127780.005555555555555556HST6/6389 9436 10008 12405 12425 12943 19091 21017 24843 25873 27981 28067 28705 28717 28741 28751 28769 28778 28868 28889 28959 28962 28974 29184 29187 29195 29202 29216 29222 29231 29233 29248 29267 29289 29294 29318 29626 29632 29636 29870 30321 30769 31043 31115 31417 33321 33330 33635 34242 37294 38465 41011 41304 41507 41522 41847 41852 42076 42314 42361 42466 42700 42761 42841 42990 44086 44220 47620 47825 47866 47868 48434 48698 48952https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/391/945?format=asciiOpticaldefaultJ/A+A/391/945/table2Main parameters of the observed clustersrecnoRecord number assigned by the VizieR team.
