Issue Date: | 2015 | Journal: | VizieR Online Data Catalog | First Page: | J/A+A/577/A132 | Abstract: | File table2 provides the coefficients of our feature ratio-temperature relations. It gives information about the features involved in the ratio (central wavelength and width), the coefficients of the best-fitting relationships, their functional form, and the corresponding standard deviation of the effective temperature calibration. <P />File table4 gives the coefficients of our spectral-type calibrations. They are expressed as third order polynomial fits. Spectral types are given in numerical form, i.e. with value 0.0 for M0, 0.5 for M0.5 and so on. A negative value implies that the star is late K-dwarf, being the index value for K7 equal to -1.0. <P />File table6 gives the coefficients of our metallicity calibrations. They have the analytical form: [Fe/H]=(A*EW)+(B*r)+C, where EW is the pseudo EW of a feature showing a strong-metallicity correlation, r is a temperature-sensitive ratio of features, and A, B, C are independent coefficients. <P />(5 data files). <P /> | URI: | http://hdl.handle.net/20.500.12386/23576 | URL: | http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=J/A+A/577/A132 | DOI: | 10.26093/cds/vizier.35770132 | Bibcode ADS: | 2015yCat..35770132M | Fulltext: | open |
