Scientific paper

Absolute U, B, V, R, I, J, H, K, and L photometry are given for a group of dwarf M and K stars. Using black-body fits to the data, bolometric luminosities and radii are derived. The derived bolometric luminosities are good to + or - 10 percent and the effective temperatures to + or - 100 K. A comparison is made with the values derived by other authors. The derived radii are 14 percent smaller than those derived from the revised Barnes et al. (1978) relation involving (V - R).
