Continuum of M 31 in the Nuclear Bulge


Sandage, Becklin, and Neugebauer (1969) have confirmed and extended the color aperture relation for M 31 over the region within T from the nucleus first reported by de Vaucouleurs and Tifft (de Vaucouleurs 1961). In view of the importance of the spectral energy distribution of M31 in determining the K correction, and also the possible variation of stellar content with distance from the nucleus, we have extended these measurements to larger apertures.
