Scientific paper

This note provides a correction to an omission in the description of the evolution of a low-mass star with halos given in the paper of Finzi (1991), where it was suggested that the average luminosity of RR Lyrae variables in the peripheral globular clusters of a galaxy exceeds by about 0.4 mag that of their counterparts at moderate galactocentric distances. It was then claimed that the comparatively large apparent luminosities of the RR Lyrae variables in the two distant satellites of M 31, NGC 147 and NGC 185, support this suggestion. This paper presents results which indicate that the luminosities in question in peripheral globular clusters and in dwarf spheroidals are not necessarily equal. An explanation of the apparently high luminosities of RR Lyrae variables in dwarf spheroidals is provided.
