cds-question@unistra.frlate-type-starsinfrared-photometryvisible-astronomybroad-band-photometrykron-cousins-photometryabsolute-magnitudeWe present a new formula for absolute magnitude determination for late-type dwarf stars as a function of (g-r) and (r-i) for Sloan photometry (as defined by Abazajian et al., 2003AJ....126.2081A). The absolute magnitudes estimated by this approach are brighter than those estimated by colour-magnitude diagrams, and they reduce the luminosity function rather close to the luminosity function of Hipparcos.2005AN....326..321Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/326/321CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/183 : UBVRI Photometric Standards (Landolt 1992)http://www.sdss.org/ : the SDSS home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AN/326/321https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/326/321http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/326/321https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/326/321https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/326/321http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/326/321GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/326/321/table1 (Sloan and UBV data for standard stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/326/321/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/326/321/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/326/321/table1?GETtext/xml+votable180.050000true10.695830.268890.0055555555555555565/7845 6/2 488 6047 8274 9157 10345 15605 17749 17840-17841 18028-18030 18069 18567 18800-18801 18826 18860-18861 19093 19095 19136 19138 20414 21844 22100 22120-22121 22242 22869 22927 22949 22960 23145 23147-23148 23705 24824 25751 25839 25849 26025 26174-26175 26260-26261 26916 26965 27045 27235 27238 30042 30121 30123 30357 30400 30833 31064-31065 31144 31470 32115 32335 34813 40430https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/326/321?format=asciiOpticalInfrareddefaultJ/AN/326/321/table1Sloan and UBV data for standard starsrecnoRecord number assigned by the VizieR team.
