CO line excitation (R52) as a function of a proxy for heavy obscuration (LIR, AGN/L2 − 10 keV). LIR, AGN and L2 − 10 keV have both been corrected to the total bolometric output by factors of 1.5 and 22.5, respectively. The symbols represent our sample at z ∼ 1.2 and are color coded as in the previous figures.
