The recent analysis by Olsen (1983) of uvby data demonstrates the difficulty of comparing observations obtained with different equipment. He detected systematic errors in the standard stars of Crawford and Barnes (1970), who merged several sources. The introduction of new photometers with quasi-rectangular passbands (Nielsen 1983), which give theoretically nontransformable output, (Young 1974), could make the problem more acute.
