Descripción
Results from UV, optical and near-IR simultaneous observations for 11 BL
Lac objects are reported. The authors find that for all but one source
the spectral flux distribution can be described by a single power law
(fν ∝ ν-α) plus, where relevant,
the contribution of the host galaxy. The comparison of the
optical-near-IR and UV spectral indices for two samples of BL Lacs
suggests the same picture for a larger sample of objects.
