Ratio between Band 3 and PILS column density ratios with respect to methanol (i.e., the ratio of blue to pink from the left panel of Fig. 2). The horizontal dashed line indicates where the ratio between Band 3 and PILS are the same. The shaded gray area indicates the region with a factor of two difference between Band 3 and PILS results. The species are ordered in the same way as in the left panel of Fig. 2. The hollow symbols show the species that have only one detected line.
