The accuracy of some of the analytic formulas for thermal cyclotron absorption coefficients is checked for temperatures in the range of 5-50 keV. It is suggested that the Robinson and Melrose (1984) analytic formulas provide the best accuracy for these absorption coefficients at large viewing angles theta with the magnetic field and sufficiently high harmonics where the harmonic structure is unimportant. It is shown, however, that their formulas are much less accurate for small theta (less than about 30 deg) than has been previously thought. In order to facilitate comparisons with the literature the cyclotron absorption coefficient has been calculated numerically by two independent methods: the dielectric tensor method of Tamor and the single-particle method. Excellent agreement is found between these methods, but a number of discrepancies with other calculations remain. Extensive opacity tables are presented for cyclotron harmonics up to about 25 at temperatures 5, 10, 15, 20, and 25 keV.
