Rest-frame UV properties are quoted from Matsuoka et al. (2018c) and Onoue et al. (2019). The coordinates are updated after tying astrometric calibrations to the Gaia database.
The Mg ii redshifts are 6.148 (J1208|$-$|0200) and 6.246 (J2239|$+$|0207), respectively (Onoue et al. 2019). We did not obtain these Mg ii measurements in hand at the time of our ALMA observations.
