cds-question@unistra.frccd-photometryvisible-astronomyAlthough a catalogue of synthetic RGB magnitudes, providing photometric data for a sample of 1346 bright stars, has been recently published, its usefulness is still limited due to the small number of reference stars available, considering that they are distributed throughout the whole celestial sphere, and the fact that they are restricted to Johnson V<6.6mag. This work presents synthetic RGB magnitudes for ~15 million stars brighter than Gaia G=18mag, making use of a calibration between the RGB magnitudes of the reference bright star sample and the corresponding high quality photometric G, G_BP and G_RP magnitudes provided by the Gaia EDR3. The calibration has been restricted to stars exhibiting -0.5<G_BP_-G_RP_<2.0mag, and aims to predict RGB magnitudes within an error interval of +/-0.1mag. Since the reference bright star sample is dominated by nearby stars with slightly undersolar metallicity, systematic variations in the predictions are expected, as modelled with the help of stellar atmosphere models. These deviations are constrained to the +/-0.1mag interval when applying the calibration only to stars scarcely affected by interstellar extinction and with metallicity compatible with the median value for the bright star sample. The large number of Gaia sources available in each region of the sky should guarantee high-quality RGB photometric calibrations.2021MNRAS.507..318Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/507/318CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/350 : Gaia EDR3 (Gaia Collaboration, 2020)I/354 : StarHorse2, Gaia EDR3 photo-astrometric distances (Anders+, 2022)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/507/318https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/507/318http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/507/318https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/507/318https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/507/318http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/507/318GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/507/318/table2 (Catalogue with RGB magnitudes for ~15 million stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/507/318/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/507/318/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/507/318/table2?GETtext/xml+votable180.050000true9.5821e-0534.9876309140.0055555555555555560/1-4 6 8-9 11 1/2 20-21 31 40 42 2/2-3 5-6 13 15 88-90 92-93 95 113 116-117 119 122-123 164-166 172 174-175 3/0 2-3 6-7 29-31 56 58-59 364-365 376-378 448-449 451 473 475 482-483 485-487 668-670 692 694-695 4/4 6 17-19 22 64 66 69 72 74-75 78 113 115 192-194 200 202-203 206-207 228 230-231 1464-1466 1800-1802 1824 1826-1827 1829-1834 1836-1837 1840 1842 1844 1855 1888-1889 1899 1922 1927 1938 2684 2772 2774-2775 5/20 22-23 29-30 65-67 80 82 84 86-87 92 94-95 260 262 268 271-272 274 280-282 285 293-295 304 306-307 309 311 317 319 448-450 456-457 459 780 782-784 786-787 789 793-795 797-799 804 806-807 818-819 821-823 916-917 919 5868 5870-5872 5874-5877 5879-5880 5883-5886 6064 6066-6069 6072-6074 6076 6078-6079 7212-7214 7300-7302 7313-7315 7341-7343 7352-7353 7355-7358 7364-7366 7373-7374 7381 7383 7389 7392 7394 7400 7408 7411-7412 7414-7415 7417-7418 7560-7561 7565-7567 7584 7586 7588-7589 7591 7593-7595 7681 7683-7684 7686-7687 7692 7694-7697 7700-7702 7704 7706-7707 7747 7751 7757-7759 10740-10741 10743 10746-10747 10750 11092 11094-11095 6/84-86 112-114 125 127 256-257 259 324 326 332 334-335 341-343 373-375 1045-1047 1052-1053 1055 1079-1081 1083 1092 1094-1095 1101-1103 1132-1133 1136-1137 1139 1145-1148 1151 1168-1169 1171 1220 1222-1223 1232 1234-1235 1240 1264-1266 1272 1804-1805 1807 1832 1834-1835 3124 3126-3127 3140 3142-3143 3153-3155 3160 3163 3165-3166 3168-3170 3184-3186 3220 3223 3265-3269 3271 3280-3281 3283 3672 3674-3675 23477-23479 23493-23495 23513-23515 23524-23526 23529-23531 23548-23550 24260-24262 24280 24282-24285 24287 24300-24301 24303 24308 24310-24311 28860-28862 29212 29214-29215 29249-29251 29360-29362 29416-29417 29436-29438 29468-29470 29488 29490-29491 29500-29502 29520-29522 29528 29530-29531 29538 29540-29541 29548 29552-29553 29555 29563-29565 29572 29574 29580-29582 29587 29590-29592 29597-29599 29604 29608 29610-29613 29619-29620 29627-29628 29630 29636 29638 29640-29641 29643 29652 29654 29664-29666 29676 29679 30248 30250-30251 30253 30255-30256 30258-30259 30340 30342-30343 30348 30350-30351 30361 30363 30368 30371 30721-30723 30728 30730-30731 30740 30742-30743 30773-30775 30792-30794 30796-30797 30799 30812 30814-30815 30821-30823 30976-30977 30982-30983 30985 30987 30994-30995 30997 30999-31002 31024 31026 42968-42970 42976 42980-42981 42983 42995 42997-42999 43004-43006 44374-443751.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/507/318?format=asciiOpticaldefaultJ/MNRAS/507/318/table2Catalogue with RGB magnitudes for ~15 million stars_RA.icrsRight ascension (ICRS) at Epoch=J2016.
