Table 7.

FIR luminosities, FIR-based star formation rates and dust masses for the RL quasars in our sample, calculated considering the total measured ALMA flux density (tot) and by correcting for the extrapolated synchrotron flux (syn).

Notes.

^(†)

The synchrotron contribution could amount to almost all the flux density at ∼300 GHz for this source. Hence, we report in this case only the IR values obtained from considering the total measured ALMA flux density as due to the dust, and use them as upper limits.
