Abstract:
New flux data are presented for nine non-variable stars and 14 evolved
variable stars with spectral types M and C. The data are from
measurements of 21 passbands in the wavelength range from 7440Å to
10834Å, and they are comparable to measurements made by Wing some
40 years ago. Because the extinction algorithm applied to the new data
is based partly on up-to-date calculations of telluric water-vapor
effects, those calculations are tested for accuracy. In addition,
methods used to calibrate standard stars both outside and inside the
Paschen confluence are explained. After reddening corrections are
applied to the flux data for the variable stars, those data are used
to calculate color temperatures. In turn, those temperatures are used
to derive blanketing corrections to color temperatures measured in the
Wing filter system. Indices of absorption strength are calculated by
comparing the flux data to blackbody colors derived from the color
temperatures. It is found that the standard errors of those
temperatures range from 3% to less than 1%. For the variable stars,
the standard errors for the flux data range from 6.8mmag to 11.6mmag.
For the non-variable stars, the corresponding standard error is about
6.0mmag.
