摘要
A calibration presented in a previous paper is used in this paper to derive temperatures for FGK stars near the main sequence. The calibration is checked against published counterparts, and it is found that previous calibrations have not established K-dwarf temperatures in particular beyond reasonable doubt. The database assembled to derive the temperatures is described, and the problems posed by close binaries are evaluated. The newly derived temperatures are used to check a line-depth ratio proposed as a thermometer by Gray and Johanson (1991, PASP, 103, 439), and it is found that the ratio is metallicity-sensitive. Temperatures are given for a total of 417 stars.
