Abstract

The catalog of 101 stars provides standards of spectral type in the sequence from MS through S and SC to the carbon stars with weak C2 bands. In addition to temperature types and C/O indices, intensities of ZrO, TiO, Na D lines, YO, and Li 6708 are given whenever possible. For variables of large amplitude the observations at different dates are tabulated.
