cds-question@unistra.frglobular-star-clustersphotometryWe present VI photometry of the metal-poor inner halo globular clusters NGC 6293 and NGC 6541 using the WFPC2 on board the Hubble Space Telescope (HST). Our color-magnitude diagrams of the clusters show well-defined blue horizontal-branch populations, consistent with their low metallicities and old ages. NGC 6293 appears to have blue straggler stars in the cluster's central region. We discuss the interstellar reddening and the distance modulus of NGC 6293 and NGC 6541 and obtain E(B-V)=0.40 and (m-M)_0_=14.61 for NGC 6293 and E(B-V)=0.14 and (m-M)_0_=14.19 for NGC 6541. Our results confirm that NGC 6293 and NGC 6541 are clearly located in the Galaxy's central regions (R_GC_<=3kpc).2006AJ....132.2171Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/132/2171CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/82/71 : Deep photometry of NGC 5694 and Terzan 8 (Ortolani+, 1990)J/AJ/99/1831 : M 68 BVRI photometry (Alcaino+ 1990)J/AJ/100/1811 : UBV photometry in Ruprecht 106 (Buonanno+ 1990)J/AJ/109/269 : Photometry of NGC 5053 (Sarajedini+ 1995)J/AJ/119/2274 : JK Photometry of globular clusters M15 + M56 (Ivanov+, 2000)J/A+A/462/107 : Simulations of metal-poor star clusters (Fagiolini+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/132/2171https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/132/2171http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/132/2171https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/132/2171https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/132/2171http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/132/2171GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/132/2171/table3b (Color-magnitude diagram data for NGC 6541)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/2171/table3b?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/2171/table3b?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/2171/table3b?GETtext/xml+votable180.050000true272.0194458-43.702250.005555555555555556Cone search capability for table J/AJ/132/2171/table3a (Color-magnitude diagram data for NGC 6293)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/2171/table3a?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/2171/table3a?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/2171/table3a?GETtext/xml+votable180.050000true257.5460994-26.57734560.0055555555555555566/29195 47777https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/132/2171?format=asciiOpticaldefaultJ/AJ/132/2171/table3bColor-magnitude diagram data for NGC 6541recnoRecord number assigned by the VizieR team.
