I-band Measurements of Red Giant Variables: Methods and Photometry of 66 Stars

Moon, T. T.

New measurements of IC and V-IC are presented for 66 bright red giant variables. This is the first stage of a program to measure sufficient numbers of such stars that also have well-determined Hipparcos parallaxes with a view to calibrating the TRGB in the IC band as a tool for accurately measuring distances to nearby galaxies.
