The ratio of line depth for two spectral lines is used to determine
stellar temperatures with a precision = 10 K = 0.2 percent. For stars
between late-F and early-K spectral types, the V I 6251 to Fe I 6253
depth ratio is easy to measure. It is also applicable to other
temperature regimes if suitable lines can be found.
