Comparison between the IRAM 30 m single dish spectra from T04 (blue and red histograms) and ALMA spectra synthesized for the same positions and angular resolution (11′′). The color vertical bands indicate the location of the blue and red EHV regimes. There is a good agreement between the 30 m and ALMA spectra inside the EHV ranges, which is indicative of only minor missing flux. IRAM 30 m data in T_mb scale and ALMA data in T_B scale.
