Multifrequency observations of blazars. 5: Long-term millimeter, submillimeter, and infrared monitoring
Multifrequency monitoring data are presented for 17 blazars between 375 and 22 GHz. These data are used to study the overall flaring behavior of blazars, and, in particular, to test predictions of shock models for the early ...
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 ...
On Improving the Calibration of Millimetre and Submillimetre Photometry at the James Clerk Maxwell Telescope / JCMT
A method is described for deriving the atmospheric extinction coefficients corresponding to the passband filters in the James Clerk Maxwell Telescope (JCMT) common-user photometer. This method takes advantage of 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 ...
