cds-question@unistra.frsurveysmagellanic-cloudsThe catalog contains 1273 proven or probable Large Magellanic Cloud (LMC) members, identified on plates taken with the Curtis-Schmidt telescope at Cerro Tololo Inter-American Observatory in Chile. The stars are generally brighter than photographic magnitude 14 and are identified on charts published by Hodge and Wright (1967) and reproduced in the source publication (1970CoTol..89....1S). Approximate spectral types were determined by examination of the 580 Angstroms/mm (at H{gamma}) objective-prism spectra; approximate 1975 positions were obtained by measuring relative to the 1975 coordinate grids on the Uppsala-Mount Stromlo Atlas of the LMC (Gascoigne and Westerlund 1961), and approximate photographic magnitudes were determined by averaging image density measures from the plates and image-diameter measures on the "B" charts of Hodge and Wright (1967SAOP.4699....1H). The catalog includes an identification number (Sk), HD(E) number, Cape Photographic Durchmusterung number, right ascension and declination (equinox B1975), spectral type, photographic magnitude, and alternate identifications. The machine version, updated in September 1986, includes corrections supplied by the author in 1985; thus, it differs somewhat from the published version. Accurate positions, and cross-identifications with the modern surveys, were determined by Brian Skiff in 2008, and make up the "sk_pos.dat" file. This work is based on a file prepared through great effort by Mati Morel in 1999. Brian Skiff examined every object on DSS cut-outs to make sure the star chosen matched the Sanduleak charts. The Goddard SkyView utility was used, looking at an 0.07{deg} (4'x4') field from the DSS1 (short-V plate), DSS2 far-red, and 2MASS J-band images. These three have the shallowest effective exposure (these are bright stars!), and usually the best image quality to check for companions etc as well as star colors. Precise coordinates were then obtained via VizieR mainly from UCAC2, but occasionally elsewhere as indicated in the column 's' for each star. The list was also matched against Tycho-2 and the GSC, and the Massey et al. photometric survey from 2002ApJS..141...81M (Cat. II/236). The file "sk_pos.dat" includes also Sanduleak's original approximate spectral types, and approximative V magnitudes that Mati Morel adopted from the work of the Marseille group; some missing HD(E) and CPD names were also added. It should be noticed also that the file has 1275 entries, 3 stars being resolved into resolved pairs. The notes includes Sanduleak's original notes, as well as remarks added by Brian Skiff in the course of his verifications.1970CoTol..89....1Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/III/113ACatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=III/113Ahttps://vizier.iucaa.in/viz-bin/VizieR-2?-source=III/113Ahttp://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=III/113Ahttps://vizier.cds.unistra.fr/viz-bin/votable?-source=III/113Ahttps://vizier.iucaa.in/viz-bin/votable?-source=III/113Ahttp://vizieridia.saao.ac.za/viz-bin/votable?-source=III/113AGETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table III/113A/catalog (The catalog with accurate positions (version 2008))https://vizier.cds.unistra.fr/viz-bin/conesearch/III/113A/catalog?https://vizier.iucaa.in/viz-bin/conesearch/III/113A/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/III/113A/catalog?GETtext/xml+votable180.050000true73.5273333-65.58955560.0055555555555555564/2068 5/8263 8269 8276 8278 8280 8281 6/33046 33047 33049 33051 33072 33073 33075 33108 33110 33111 33116 33128 33133 33136 33137 33138https://cdsarc.cds.unistra.fr/viz-bin/moc/III/113A?format=asciiOpticaldefaultIII/113A/notesNotes (original and B.
