Notes. Here R1 and R2 refer to observation runs 1 and 2 with IRAM-30m. RA and Dec are expressed in the J2000 coordinate system. Object R1-0 is a radio-loud quasar, and object R2-0 is a radio galaxy. These two objects were recently classified as non-GRGs based on new available data. All the redshifts listed in Col. 5 are from spectroscopic measurements, where redshifts marked with a dagger are taken from the SDSS. In the absence of SDSS spectroscopic redshift measurement, the redshift was taken from the reporting paper (Col. 9). Columns 7 and 8 represent the WISE band 4 magnitude and luminosity, respectively.
