Bolometric Corrections from COMARCS/COMA Spectra 2010-2019

The following tables with bolometric corrections (BCs) for different photometric systems are based on COMA09/10/11/12 spectral synthesis from hydrostatic COMARCS models. Reddening due to circumstellar dust is not included. Details concerning the computations, the input physics and the application of these data can be found in the papers "Synthetic photometry for M and K giants and stellar evolution: hydrostatic dust-free model atmospheres and chemical abundances", 2016, by B. Aringer, L. Girardi, W. Nowotny, P. Marigo and A. Bressan, MNRAS 457, 3611 (MNRAS or PDF) and "Carbon stars with increased oxygen and nitrogen abundances: hydrostatic dust-free model atmospheres", 2019, by B. Aringer, P. Marigo, W. Nowotny, L. Girardi, M. Mecina and A. Nanni, MNRAS (submitted), which should also be quoted when using the presented data.

All of the tables include the following columns: effective temperature [K]; log(g) - surface gravity g [cm/s**2]; M/M(sol) - mass scaled to the solar value; o = log(eps(O)/eps(H)) + 12; c = log(eps(C)/eps(H)) + 12; fe = log(eps(Fe)/eps(H)) + 12; log(L/L(sol)) - luminosity scaled to the solar value; xi = microturbulent velocity [km/s]; BCx - bolometric corrections for all of the filters X of the corresponding system. The entries are sorted according to the file names.
