Finally there is an option to choose the '''extraction type'''. The default is to '''sum''' all of the rows within the extraction window. Note: no correction is made for spectral tilt, which may be important for users concerned with the highest possible spectral resolution. The automatic extracted spectra always use this option regardless of the setting chosen for display. The alternative choice is to only show the '''peak row'''. This can be useful when checking that the spectra are not saturating.
Finally, for an arc, most of these options are disabled. The '''arc extraction''' simply uses the '''single row''' at the mid point between the two cyan extraction edge lines. This single row extraction : minimises the potential impact of cosmic rays; the broadening of lines by summing over the tilted lines in the full window; and should provide sufficient S/N with even short exposures.
