Descripción
Optical spectroscopy of three recently discovered BL Lacs (PG 1246+586,
PG 1424+240 and PG 1437+398) in the Palomar-Green optical survey is
presented. The three sources have featureless spectra and the continuum
is well represented by a power law model with slopes typical of BL Lac
objects. The observations together with data at other frequencies
collected from the literature, are used to construct the overall energy
distribution from radio to X-ray and compared with that of all other BL
Lac in the PG survey. The overall properties of the small sample of PG
BL Lacs objects are shortly discussed.
