cds-question@unistra.frphotometric-standard-starsvisible-astronomyWide-band photometryphotographic-photometryA single table combines the revised and extended results of 24 series of photometric observations made in South Africa between 1947 and 1960 on the nine Harvard E regions at declination -45{deg}. For each of about 90 stars in each region are tabulated V and B-V on the standard U,B,V system, an ultraviolet-free blue magnitude S'Pg, a photovisual magnitude SPv and, in most cases, an ultraviolet minus blue colour (U-B)_C_. The internal standard error of an entry is +/-0.01mag or less.1962RGOB...49....3Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/II/222CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=II/222https://vizier.iucaa.in/viz-bin/VizieR-2?-source=II/222http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=II/222https://vizier.cds.unistra.fr/viz-bin/votable?-source=II/222https://vizier.iucaa.in/viz-bin/votable?-source=II/222http://vizieridia.saao.ac.za/viz-bin/votable?-source=II/222GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table II/222/ereg (Catalogue of the E regions (Table 2 and appendix combined with Table 4))https://vizier.cds.unistra.fr/viz-bin/conesearch/II/222/ereg?https://vizier.iucaa.in/viz-bin/conesearch/II/222/ereg?http://vizieridia.saao.ac.za/viz-bin/conesearch/II/222/ereg?GETtext/xml+votable180.050000true21.8959-46.14110.0055555555555555565/8583 8589 8594 8764 8765 8766 8852 9553 9632 9633 9634 9640 9869 9871 10491 10494 10572 10573 10575 10832 10890 10914 11580 11581 11618 11625 11853 11854 6/33976 34331 34352 34353 34355 34365 34371 34372 34374 34375 34380 34382 34383 34386 34392 34394 34400 34402 34408 34941 35025 35031 35035 35037 35038 35039 35053 35054 35068 35069 35070 35208 35210 35232 35234 35235 35397 35412 35414 35415 35416 35417 35440 37845 37847 37849 37852 37854 37855 37877 38165 38208 38209 38210 38216 38224 38225 38228 38441 38443 38444 38447 38458 38540 38541 38544 38545 38552 38566 39443 39446 39447 39450 39452 39453 39455 39473 39475 39480 39481 39482 39488 39490 39491 39496 39498 39499 39520 39522 39523 39569 41947 41957 41959 41962 41963 41969 41970 41971 41980 41982 41983 42268 42270 42271 42279 42285 42286 42296 42297 42299 42312 42314 42315 42318 42319 42336 42337 42338 42344 42384 42385 42388 42664 43285 43287 43293 43332 43333 43336 43338 43339 43344 43345 43346 43364 43365 43558 43559 43649 43650 43651 43652 43654 43655 43660 43662 43663 43680 43681 43688 46299 46301 46302 46303 46317 46318 46329 46331 46333 46334 46335 46479 46496 46497 46498 46506 46615 46663 47385 47389 47390 47399 47407 47411 47420 47421 47422 47459 47464 47465 47493 47494 47495 47504 47505 47507 47509 47512 475143.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/II/222?format=asciiOpticaldefaultII/222/eregCatalogue of the E regions (Table 2 and appendix combined with Table 4)HHavard lettermeta.idcharrecnoRecord number assigned by the VizieR team.
