✦ Synopsis

Zentralinstitut fiir Astrophysik der hkadcniir dcr Wissrnschaftrn drr 1>1)1< With I figure (Recrived 1984 October 28) T h e photometrically determined mean surface magnetic fields 21s need a revision. h'one of the stars for wliich BS can he measured directly by Zceinan line splitting fulfils the relation between the photometric parametcr A ( V1 -G) and the nieiin surface field 13g, which is used by SORTH, CRAMER and MAEIIER to determine h's for othcr 131 -A 3 stars. I'hc ratio ~B $ / n s for stars. which drfine North's relation. sliows unreasonable large values.
