We present Strömgren uvby photometry for a sample of 31 high Galactic latitude stars selected from the Palomar-Green Survey . The data include photometric magnitudes accurate to [FORMULA] 0.01 mag in most cases, plus colours and the reddening free [c1] and [u-b] indices, which possess a precision of better than 0.02 and 0.04 mag, respectively. The latter should be suitable for the reliable determination of stellar photometric temperatures.

Key words: stars: early-type – stars: fundamental parameters – Galaxy: halo
