We present homogeneous and standardized UBV ( RI ) C JHK photometry for over 100 M stars selected from an earlier paper on the basis of apparent photometric constancy. L photometry has been obtained for stars brighter than about L = 6 . Most of the stars have a substantial number of UBV ( RI ) C observations and, it is hoped, will prove useful as red supplementary standards. Additionally, we list JHK photometry for nearly 300 Hipparcos red stars not selected as standards, as well as L photometry for the brightest stars.
