Notes. Here, νtuning is the frequency setup of the corresponding receiver and tobs the total integration time on source. For EMIR spectra, total exposure times tobs only include scans selected for the optimal reduction. The HNC(5–4) line in PLCK_G244.8+54.9 was observed both at lower (LR) and higher (HR) spatial resolution with ALMA (see details in the text). The rms noise levels are measured on line-free spectral channels of source-integrated spectra and given for channels binned to 50–55 km s−1, 100 km s−1, and 35–40 km s−1 for IRAM-30 m/EMIR, NOEMA, and ALMA spectra, respectively. Telescope efficiencies 
listed for EMIR observations are extrapolated from the calibration tables and used to convert the line fluxes to Jy km s−1. The rms values marked with an asterisk are given in mJy rather than mK.
