cds-question@unistra.frstellar-radiiinterferometryvisible-astronomyphotometryeffective-temperaturemorgan-keenan-classificationinterstellar-reddeningWe present new angular diameter measurements for 33 stars from the Navy Precision Optical Interferometer, reaching uncertainties on the limb-darkened diameter of 2% or less for 21 targets. We also determined the physical radius, bolometric flux, luminosity, and effective temperature for each star. Our sample is a mix of giant, subgiant, and dwarf stars, and span spectral classes from mid-A to to mid-K. We combined these 33 stars with samples from previous publications to analyze how the NPOI diameters compare to those obtained using other means, namely (V-K) color, the JMMC Stellar Diameters Catalog, and Gaia predictions.2023AJ....166..268Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/166/268CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/pastel : The PASTEL catalogue (Soubiran+, 2016-)B/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2020)II/21A : Narrow-Band Photometry of Late-Type Stars (Haeggkvist+ 1970)II/84 : 13-color photometry of 1380 bright stars (Johnson+ 1975)II/7A : UBVRIJKLMNH Photoelectric Catalogue (Morel+ 1978)II/62 : Catalogue of Extinction Data (Neckel+, 1980)II/122B : UBV Photoelectric Catalog: data 1953-1985 (Mermilliod 1987)II/164 : DDO Photoelectric Photometric Catalog (Mermilliod+ 1989)III/164 : Catalog of Eq.Widths of Interstellar 217nm Band (Friedemann 1992)I/259 : The Tycho-2 Catalogue (Hog+ 2000)III/232 : STELIB: A library of stellar spectra at R~2000 (Le Borgne+, 2003)I/284 : The USNO-B1.0 Catalog (Monet+ 2003)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)I/345 : Gaia DR2 (Gaia Collaboration, 2018)II/361 : MDFC Version 10 (Cruzalebes+, 2019)V/137D : Extended Hipparcos Compilation (XHIP) (Anderson+, 2012)VI/137 : GaiaSimu Universe Model Snapshot (Robin+, 2012)J/A+AS/117/227 : Dwarf effective temperatures (Alonso+ 1996)J/PASP/110/863 : A Stellar Spectral Flux Library: 1150 - 25000 A (Pickles 1998)J/A+A/352/555 : Fundamental parameters of stars (Allende Prieto+, 1999)J/AJ/117/1890 : Hipparcos binaries (Mason+, 1999)J/AJ/127/1227 : Synthetic Stroemgren photometry (Clem+, 2004)J/ApJS/154/673 : COBE DIRBE Point Source Catalog (Smith+, 2004)J/ApJS/152/251 : Indo-US library of coude feed stellar spectra (Valdes+, 2004)J/A+A/430/165 : Radial velocities for 6691 K and M giants (Famaey+, 2005)J/A+A/434/1201 : ESO VLTI Calibrators Program (Richichi+, 2005)J/A+A/431/773 : CHARM2, an updated of CHARM catalog (Richichi+, 2005)J/MNRAS/367/1478 : Interstellar NaI, TiII & CaIIK obs.
