Notes. We list line ratios derived in the CND of NGC 1068 (NGC 1068-CND), the B1 and B2 bullets of the young stellar object L1157, as well as the nuclear disk and Northern spiral arm of the nearby galaxy IC 342 (IC 342-Ndisk and IC 342-N arm, respectively). Line ratios are given in units; these are corrected by source coupling factors for single-dish observations. Uncorrected ratios are identified by an asterisk; corrected ratios (in -source units) are given in parentheses when necessary.
