Comparison of molecular column densities in CIT 6 and IRC+10216 derived from our survey data. The dashed red line marks the one-to-one relation, where both sources have equal column densities. The dashed yellow line indicates where column densities in CIT 6 are two times lower than in IRC+10216, while the dashed green line shows the case where column densities in CIT 6 are ten times lower. Most species are less abundant in CIT 6 by factors of 2-10, while a few (e.g. SiO) show comparable column densities. A detailed breakdown of relative abundances with respect to HC₃N, C³⁴S, and SiO is provided in Table 7 and 8.
