Scientific paper

The authors report accidental errors and blanketing sensitivities for seven disk K giant temperature indices: Johnson J-K, Cousins R-I, Johnson R-I, Kron R-I, the Spinrad-Taylor T index. T1-T2, and V-K. The authors ultimately compare these indices to a blanketing-free color index, with the latter being derived from narrowband photometry, empirical blocking data, and a model-atmosphere backwarming correction. They also investigate the anomalous R band blanketing reported by Frogel, Whitford, and Rich for Baade's Window K giants.
