In particular, the filter was Stromgren's b. For 12 (DD) Lac, there are 323 differential magnitudes "12 Lac minus 10 Lac" (Table 1). For 16 (EN) Lac, there are 278 differential magnitudes "16 Lac minus 2 And" (Table 2). The observers were E. Szuszkiewicz, B. Musielok, S. Ratajczyk, M. Tomczak and J. Wlodarczyk. E.
