cds-question@unistra.frmilky-way-galaxyglobular-star-clustersextinctionExtensive photometric studies of the globular clusters located toward the center of the Milky Way have been historically neglected. The presence of patchy differential reddening in front of these clusters has proven to be a significant obstacle to their detailed study. We present here a well defined and reasonably homogeneous photometric database for 25 of the brightest Galactic globular clusters located in the direction of the inner Galaxy. These data were obtained in the B, V, and I bands using the Magellan 6.5m Telescope and the Hubble Space Telescope. A new technique is extensively used in this paper to map the differential reddening in the individual cluster fields, and to produce cleaner, dereddened color-magnitude diagrams for all the clusters in the database. Subsequent papers will detail the astrophysical analysis of the cluster populations, and the properties of the obscuring material along the clusters' lines of sight.2012AJ....143...70Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/143/70CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)VII/202 : Globular Clusters in the Milky Way (Harris, 1997)VII/103 : Galactic Globular Clusters (Monella 1985)J/AJ/140/1043 : GCs in M31 and the Galaxy (van den Bergh+, 2010)J/AJ/133/1287 : JHK photometry of 24 Galactic GCs (Valenti+, 2007)J/A+A/450/105 : Properties of 153 Galactic globular clusters (Bica+, 2006)J/AJ/132/2171 : VI photometry of NGC 6293 and NGC 6541 (Lee+, 2006)J/ApJ/628/729 : CCD BVIc photometry of M10 stars (Pollard+, 2005)J/ApJ/608/243 : CCD BVI photometry of M12 stars (Hargis+, 2004)J/MNRAS/349/1278 : BVI photometry of M22 (Monaco+, 2004)J/AJ/124/1486 : M4 UBV color-magnitude diagrams (Mochejska+, 2002)J/A+A/391/945 : HST photometry of 74 galactic GCs (Piotto+, 2002)J/AJ/121/916 : HST obs. of NGC 2298, 5897, 6535, and 6626 (Testa+, 2001)J/A+AS/145/451 : Nearby GCs photometric catalog (Rosenberg+, 2000)J/A+AS/144/5 : Nearby GCs photometric catalog (Rosenberg+, 2000)J/A+AS/135/391 : VI CCD photometry of NGC 6553 (Sagar+ 1999)J/A+A/331/70 : JKVI photometry of NGC 6553 stars (Guarnieri+ 1998)J/AJ/110/652 : VI photometry in NGC 6352 (Fullton+ 1995)J/ApJS/93/161 : CCD photometry of 6 globular clusters (Sarajedini+ 1994)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/143/70https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/143/70http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/143/70https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/143/70https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/143/70http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/143/70GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/143/70/table1 (Characteristics of the globular clusters in our sample according to the 2010 version of the Harris (1996, Cat.
