Landolt's natural GaAs u - b system is not very close to the standard U - B system and so it is likely that, because the transformations were made using a U - B colour term alone, systematic U - B differences exist for some kinds of stars namely, A-F stars, reddened B-A stars and giant A-F stars. ...
