Infrared luminosities derived using different approaches vs. the IR luminosity derived in Sect. 6 for our entire sample. The black squares show L_IR derived using a modified blackbody, the red circles show L_IR derived from the monochromatic luminosity from ALMA band 9, and blue stars show those derived from the monochromatic luminosity from ALMA band 7. The black line is the identity line, and the dashed black, solid red, and dotted blue lines represent the best fit of each inferred L_IR.
