- W89100269 abstract "A survey for variable quasars over an 18 deg 2 field was started in 1977 with the UK 1.2 m Schmidt telescope. In the course of the survey, we have found 23 objects with a variability amplitude ΔB≥1 mag. Spectroscopic observations of 14 of them have shown that two have featureless spectra ; both have a high degree of optical polarization (5.9 and 9.6% respectively), and both are radio sources with a flat spectrum between 843 and 4790 MHz. There is no doubt that they are BL Lac objects. The minimum corresponding surface density of ∼0.1 deg −2 at B∼19 is equal to the upper limit derived by Woltjer & Setti in 1982" @default.
