Description:
The authors have classified 176 IRAS sources as carbon stars based on
the presence of the SiC emission feature at 11.2 micron in their
low-resolution spectra (LRS).
Accurate positions were found by B. Skiff (Lowell Obs.), using
visible-light (DSS), 2MASS, and WISE images to identify the carbon
stars. Many of the stars are large-amplitude variables, whether
designated or not, so sometimes the magnitudes are rounded to a whole
magnitude so as to be representative of the brightness. Some notes are
added about close companions and two stars where the existing position
is significantly in error.
