Abstract
The authors present single-epoch multifrequency data for the radio-quiet
low-redshift QSO Ton 1542, spanning radio through ultraviolet
wavelengths. They measure a 3σ upper limit of 9.2 mJy for the 20.3
GHz flux density. The first ultraviolet spectrum of this object is
presented and discussed. The authors find a particularly strong excess
of flux density at ≡3000 Å, which is likely to be dominated
by Balmer continuum emission. They also find a Lα/Hβ flux
ratio of ≡17, which is higher than that usually observed in QSOs.
