Scientific paper

Electrophotometry for nine stars of the RR Lyrae class in UVbY-beta are presented with a view to the behavior of the Delta-S metallicity parameter over the course of light change. An analysis of the data thus obtained indicates that the variables for which Delta-S variation with light phase was established do not show any variations of the metallicity index m(1). A tabulation is presented of normal curves for RZ Cep, XZ Dra, SE Lyn, TT Lyn, RR Lyr, AV Peg, BH Peg, DH Peg, and TU UMa.
