4.3.5 Secondary calibrators & pointing sources

If during your observing run no planets are available, or they are too close to the sun, you should observe secondary calibrators in order to properly calibrate your data. Most sources with $S \ge 5\,{\rm Jy}$ in the following table are also excellent pointing sources. Ask the FoT on duty if you're not sure about a particular source.
The last entry in each line gives the measured flux density at 345GHz.

Please note that while we try to provide reliable flux density values for these sources, we do not monitor them. Some sources, like 3C279, may be variable. We remind you that proper data calibration is your responsibility!
