Phase Calibrator List

The current list of phase calibrators used at Plateau de Bure includes over 300 objects. Flux densities at 85 GHz flux are indicated in Jy. The flux densitiy is followed by the spectral index or 0 if no measurement is available. Be careful: most if not all sources are variable (both flux and spectral index vary). All coordinates are Equatorial J2000.0. Bandpass calibrators should be selected among the strongest phase calibrators, 4Jy or more if possible, but even 0.5Jy sources are sufficiently strong as phase calibrator at 3mm. At 1.3mm, sources above 1Jy should be preferred.

The planets are not sufficiently point-like to be used as bandpass calibrators in any configuration.

To find phase calibrators for your source, use the ASTRO procedure name PR:FIND_CALI.ASTRO.
