cds-question@unistra.frvariable-starsglobular-star-clustersccd-photometryPhotometry is presented for the RR Lyrae variables in the Large Magellanic Cloud (LMC) cluster NGC 1835. Sixteen new variables have been discovered. Due to the extreme crowding of the LMC field stars, the scatter of the light curves and mean magnitudes is greater than that found for other LMC clusters studied under similar conditions. The derived parameters of the light curves yield E(B-V) = 0.13 and [Fe/H] = -1.8, consistent with previous measurements. The complete sample of RR Lyraes has mean magnitudes <V> = 19.38, <B> = 19.70. If a distance modulus of 18.5 mag for the LMC is assumed, then in the mean the NGC 1835 RR Lyraes have <Mv> = 0.48, almost identical to the average found by the same procedure for the six other LMC clusters.1993AJ....105..527Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/105/527CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/AJ/112/2020 : UBV Photometry of NGC 1841 (Alcaino+ 1996)J/PASP/104/1063 : BV Color-Magnitude Diagram for NGC 1851 (Walker 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/105/527https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/105/527http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/105/527https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/105/527https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/105/527http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/105/527GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/105/527/table3RR Lyr var. photometryGR/V22BGR/V22 B magnitudemagphot.mag;em.opt.BfloatGR/V23VGR/V23 V magnitudemagphot.mag;em.opt.VfloatGR/V23BGR/V23 B magnitudemagphot.mag;em.opt.BfloatGR/V24V[]?
