These atmospheres are representative of larger grids that are currently being completed. We discuss differences between the different grids and compare theoretical color-temperature relations and the fundamental color temperature relations derived from: (a) the infrared-flux method (IRFM) for A-K stars (Blackwell & Lynas-Gray 1994A&A...282..899B; Alonso et al. 1996A&AS..117..227A) and M dwarfs (Tsuji et al. 1996A&A...305L...1T); (b) lunar occultations (Ridgway et al. 1980ApJ...235..126R) and (c) Michelson interferometry (Di Benedetto & Rabbia 1987A&A...188..114D; Dyck et al. 1996AJ....111.1705D; Perrin et al. 1998A&A...331..619P) for K-M giants, and (d) eclipsing binaries for M dwarfs. We also compare color-color relations and color-bolometric correction relations and find good agreement except for a few colors. The more realistic fluxes and spectra of the new model grids should enable accurate population synthesis models to be derived and permit the ready calibration of non-standard photometric passbands. As well, the theoretical bolometric corrections and temperature-color relations will permit reliable transformation from observed color magnitude diagrams to theoretical HR diagrams.1998A&A...333..231Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/333/231CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/39 : Model Atmospheres (Kurucz, 1979)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/333/231https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/333/231http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/333/231https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/333/231https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/333/231http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/333/231GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/A+A/333/231/table1Color indices and bolometric corrections from ATLAS9 overshoot models (Kurucz, 1995a, priv. comm.)recnoRecord number assigned by the VizieR team.
