cds-question@unistra.frglobular-star-clustersinfrared-photometryvisible-astronomyphotometryWe carried out VRI and Gunn z observations of the obscured globular cluster Liller 1. The cluster is so reddened (A_V_=~9.0) that it is at the detection limit in V. The RGB in I vs. (I-z) shows a strong curvature. Recalling that the nearly solar metallicity globular clusters NGC 6553 and NGC 6528 present similar blanketing effects only in the visible bandpasses, we conclude that Liller 1 is considerably more metal-rich than these clusters. The CMD comparison of Liller 1 with the inner bulge field around it (located =~5deg from the nucleus), suggests that the cluster is as metallic as the most metallic fraction of this inner bulge population. Similarly deep I and z observations at =~0.5deg away from Liller 1, at the nominal position of Grindlay 1 do not reveal any cluster.1996A&A...306..134Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/306/134CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/306/134https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/306/134http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/306/134https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/306/134https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/306/134http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/306/134GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/306/134/table2I, Gunn z photometry of Liller1recnoRecord number assigned by the VizieR team.
