In Table 1, the catalogue of Strömgren uvby photometry for 283 program stars is presented. The PPM identifications are given in the first column. Columns 2, 4, 6 and 8 give V, b-y, m₁ and c₁. Columns 3, 5, 7 and 9 present the internal rms errors of one observation (weight 1). In Cols. 10 and 11 the weight of V and the indices are listed. Column 12 gives the number of nights for each star.

Table 2 gives H$\beta$ photometry for 225 program stars. The PPM identifications are given in the first column, and the photometry, the internal rms errors of one observation (weight 1), the weight of the H$\beta$indices and the number of the nights for each star follow. The cross-identification with the HD and LS numbers is available in the last two columns of the tables.
