Notes.
To increase the S/N ratio, we include the adjacent two pixels in the extraction for the SN region.
The double horizontal line separates the nebular lines that were taken in the two different FORS2 observational setups. As a result of the different width of the line spread function and thus angular scales probed in both setups, the emission lines below and above the horizontal line cannot easily be used together to infer physical properties.
