Notes. (a): Whole sample, regularized rms weighted average. (b): All objects except CFHQS J0221−802 and CFHQS J0316−1340 whose 250 GHz rms are peculiarly large; straight average (with equal weight for all sources). (c): All objects except CFHQS J1429+5447 which is exceptionally strong at 250 GHz and radio loud (Sect. 3.2); regularized rms. (d): All objects except CFHQS J0033-0125, CFHQS J0102-0218, and CFHQS J1429+5447 which are (tentatively) detected; regularized rms. (e): Same as c), but m1450 < 21.7. (f): Same as c), but m1450 > 21.7.

(*)

Bolometric luminosity: av mean value (straight average, with equal weight for all sources); med median value.

(†)

Averages of S250  GHz are performed as described in Sect. 3.2: groups a to f.

(#)

The value used for LFIR of CFHQS J1429+5447 corresponds to the totality of the measured 250 GHz flux density, while only an unknown part is emitted by the starburst dust in the quasar host galaxy.

(††)

⟨LFIR⟩ is inferred from through Eq. (1) (for all groups with several sources, the average redshift ⟨ z ⟩  = 6.09 is assumed); ⟨Mdust⟩ is inferred from ⟨LFIR⟩ through Eq. (2).
