Walraven VBLUW photometry in Basel halo fields. I - Photometric data for selected areas SA141 (South Galactic Pole), SA94 and SA107
In 1981 a joint Swiss-Dutch program was initated to obtain photoelectricphotometry in the Walraven VBLUW system for F-G stars in fields of theBasel halo survey. The aim of this project is to determine temperature,surface gravity, and metal abundance for these stars in order to studythe distribution of the average stellar metallicity as a function ofdistance from the galactic place up to z-distances of about 1 kpc. Thispaper presents the VBLUW data for 112 program stars in Selected AreaSA141 at the South Galactic Pole, 93 stars in SA94 (l = 175 deg, b = -49deg), and 46 stars in SA107 (l = 6 deg, b = +41 deg).
