Scientific paper

It was suggested by Baade (1958) that the nucleus of M31 is a separate structure, independent of the bulge. Attention is presently given to the nuclear structure derived for M31 on the basis of ground-based CCD observations made by Kent (1983), which were digitally deconvolved from the asymmetrical point spread function taking ellipticity into account. A comparison with the photographic measurements of Johnson (1961) and the extraatmospheric measurements of Light, et al., (1974) yields satisfactory agreement, in view of the uncertainties of the various types of observation.
