The 1993 multiwavelength campaign on 3C 279 : the radio to gamma-ray energy distribution inlow state
Simultaneous observations of 3C 279 at radio, millimeter, near-infrared, optical, ultraviolet (with IUE) and X-ray (with ROSAT) wavelengths were obtained in 1992 December-1993 January, during a three week pointing at the ...
Infrared Photometry of Blazars - 8 Years of Observations
We present photometric observations of 16 blazar sources at mid- to near- infrared wavelengths, covering the period 1986 January to 1993 December. We present the data in tabular form and, for selected well-sampled sources, ...
A Comparison of the Radio / Submillimetre Spectra of Bl-Lacertae Objects and Flat Spectrum Radio Quasars
We present quasi-simultaneous radio, millimetre and submillimetre spectra of 22 BL Lac objects and 24 radio-loud, violently variable quasars. These data are used to test the hypothesis that BL Lacs and OVV quasars are ...
