Notes. Classification of emission is ‘oc’, ‘sc’, ‘oe’ and ‘se’, where ‘s’ and ‘o’ is if the emission peaks on- or off source, respectively, while ‘c’ and ‘e’ is whether the emission is compact or extended. ‘x’ is for non-detections. (a)S/N too low to make an emission map. The emission is assumed to be compact and on source (‘sc’) as for most other molecules detected towards S26, and ‘se’ for N63. For HDO towards N12 we assume emission to be off source and extended, similar to HDO emission towards N30. For N63 the S/N is too low for OC34S and CH3CN to be sure if the emission is extended or not. It is therefore assumed to be as extended as the other molecules in this source.
