cds-question@unistra.frdwarf-starsgiant-starsstellar-radiiinterferometrySurface brightness-colour relations (SBCRs) are used to derive the stellar angular diameters from photometric observations. They have various astrophysical applications, such as the distance determination of eclipsing binaries or the determination of exoplanet parameters. However, strong discrepancies between the SBCRs still exist in the literature, in particular for early and late-type stars. We aim at calibrating new SBCRs as a function of the spectral type and the luminosity class of the stars. Our purpose is also to apply homogeneous criteria for the selection of the reference stars and on the basis of an exhaustive and up-to-date list of interferometric late-type targets. We implement criteria to select measurements in the JMMC Measured Diameters Catalog (JMDC). We then apply additional criteria on the photometric measurements used to build the SBCRs, together with stellar characteristics diagnostics. We build SBCRs for F5/K7-II/III, F5/K7-IV/V, M-II/III and M-V stars, with respective RMS of {sigma}_FV_=0.0022mag, {sigma}_FV_ =0.0044mag, {sigma}_FV_=0.0046mag, and {sigma}_FV_=0.0038mag. This results in a precision on the angular diameter of 1.0%, 2.0%, 2.1% and 1.7%, respectively. These relations cover a large V-K colour range of magnitude, from 1 to 7.5. Our work demonstrates that SBCRs are significantly dependent on the spectral type and the luminosity class of the star. Through a new set of interferometric measurements, we demonstrate the critical importance of the selection criteria proposed for the calibration of SBCR. Finally, using the Gaia photometry for our samples, we obtain (G-K) SBCRs with a precision on the angular diameter between 1.1% and 2.4%. By adopting a refined and homogeneous methodology we show that the spectral type and the class of the star should be considered when applying a SBCR. This is particularly important in the context of PLATO.2020A&A...640A...2Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/640/A2CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/345 : JMDC: JMMC Measured Stellar Diameters Catalogue (Duvert, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/640/A2https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/640/A2http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/640/A2https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/640/A2https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/640/A2http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/640/A2GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/640/A2/dwarfs (F5/K7-IV/V sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/640/A2/dwarfs?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/640/A2/dwarfs?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/640/A2/dwarfs?GETtext/xml+votable180.050000true175.262566434.20163390.005555555555555556Cone search capability for table J/A+A/640/A2/giants (F5/K7-II/III sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/640/A2/giants?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/640/A2/giants?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/640/A2/giants?GETtext/xml+votable180.050000true173.2504794-31.85762310.005555555555555556Cone search capability for table J/A+A/640/A2/m_dwarfs (M-V sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/640/A2/m_dwarfs?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/640/A2/m_dwarfs?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/640/A2/m_dwarfs?GETtext/xml+votable180.050000true77.9191222-45.01843170.005555555555555556Cone search capability for table J/A+A/640/A2/m_giants (M-II/III sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/640/A2/m_giants?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/640/A2/m_giants?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/640/A2/m_giants?GETtext/xml+votable180.050000true172.850919769.3310750.0055555555555555566/15 128 137 377 428 679 684 737 845-846 871 915 998 1015 1143 1341 1399 1410 1853 2282 2317 2691 2737 2837 2923 2927 2958 2973 3026 3034 3036 3058 3102 3118 3146 3160 3184 3229 3259 3536 3602 3616 3619 3639 3657 3682 3714 3733 3762 4146 4438 4559 4574 4578 4854 4990 5009 5109 5245 5304 5382 5420 5534-5535 5587 5670 5718 5853 5982-5983 6066 6510 7006 7238 7264 7545 7760 7937 8476 8671 8767 8834 8845 8986 8995 9083 9092 9127 9213 9327 9403 9476 9520 9610 9662 9712 9717 9753 9813 9843 10003 10055 10084 10367 10375 10380 10899 11352 11403 11473 11479 11519 11547 11598 11633 11636 11658 11732 11734 11756 11874 11910 11958 11964 11987 12021 12030 12056 12082 12465 12482 12544 12612 12770 12944 12953 12960 12962 13198 13282 13301 13332-13333 13363 13392 13440 13550 13643 13778 14005 14064 14084 14144 14180 14198 14220 14239 14278 14280 14287 14373 14396 14419 14434 14631 14653 14699 14704 14757 14767 14878 14917 14968 15044 15174 15176 15203 15227 15273 15302-15303 15311 15356 15371 15441 15500 15567 15597 15602 15719 15882 15885 15895 16023 16035 16069 16148 16192 16391 16689 16834 17262 17266 17425 17496 17568 17608 17716 17723 17752 18104 18139 18204 18496 18547 18688 18702 18893 19286 19323 19585 19825 19879 19912 20100 20145 20308 20328 20368 20809 21060 21182 21423 21457 21477 21484 21768 21941 22015 22199 22300 22309 22420 22518 22705 22708 22807 22964 23140 23190 23201 23230 23283 23344 23369 23423 23540 23753 23765 23820 23875 23995-23996 24151-24152 24545 24557 24715 24924 25805 26320 26521 26552 26575 26583 26952 26972 26975 27198 27220 27392 27462 27553 27568 27694 28364 28487 28605 28664 28948 28955 29589 29926 30228 30339 30419 30476 30529 30541 30567 30665 30771 30878 30958 30965 31187 31416 31433 31475 31576 31751 31781 31784 32182 32192 32271 32477 32645 32652 32754 32891 32994 33228 33249 33377 33874 34051 34169 34181 34263 34510 34730 35025 35185 35382 35415 35532 35602 35673 35984 36317 36433 36451 36635 36693 36723 36803 37507 37778 39026 39340 39611 39861 39888 40618 40692 40749 40795 41270 41591 41763 42046 42290 44248 44284 44542 44921 45564 45668 46176 46566 46582 46632 47423 47728 48519 490607.952274030004205e-20 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/640/A2?format=asciidefaultJ/A+A/640/A2/dwarfsF5/K7-IV/V sampleNameStar IDmeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
