User:Gaba p/Washington Photometric System

The Washington photometric system is a broadband photometric system, initially designed by G. Wallerstein and later developed by R. Canterna at the Kitt Peak National Observatory, aimed at obtaining accurate photometric temperatures, metal abundances, and a cyanogen blanketing index for G and K type giant stars. It is composed of four main filters: C, M, T1 and T2 of effective wavelengths 3910, 5085, 6330 and 7885 Å respectively. Most of its colors can be well transformed into related colors in the Cousins BVRI system.
