The Wing photometric system

Basic Reference

White N.M., Wing R.F. 1978, ApJ 222, 209

Abstract

A photoelectric system defined by eight narrow bands between 0.7 and 1.1 micron has been used to measure nearly all M supergiants that have been classified on the MK system. The photometric TiO and CN indices reproduce the two-dimentional MK classifications to the accuracy of the MK types themselves. Mean fluxes and spectral classifications are presented for 128 stars.
