Infrared fluxes, spectral types, and temperatures for very cool stars

From narrow- and broad-band photometry between 0.55 and 10.2, complete energy distributions, photometric spectral types, and total fluxes are derived for a sample of cool giants, Mira variables, and IRC stars. From stars lacking infrared excesses, an intrinsic relation for color temperature versus spectral type is found for stars as well as bolometric corrections for the fluxes at 1.04 and 2.2. The effective temperature scale for cool stars is reexamined and its sources of error are discussed. Subject headings: infrared sources - late-type stars - long-period variables - photometry
