Notes to the table: $\times =$ detected, $-\times$ means observed but not detected. 
\molh\ indicates the presence of ro-vibrationally excited \molh\ lines; [Fe~II] the presence of [Fe~II]~lines; \molh~+ [Fe~II] the presence of both species along the same line of sight/inside spectrograph slit. When possible, HH-nomenclature follows that of \citet{reipurth1999}. \\
