The profile pane shows a cross section in the spatial direction through the spectrum. This controls the regions used for extraction and sky subtraction of the science data. The default is to search for the '''highest peak''' in the spectrum automatically and to fit a region +/-2 sigma around a Gaussian fit to this peak. An alternative is to choose the '''most central peak''', assuming observers try to centre the object within this slit. This setting is useful when a brighter object than the intended target falls within the slit. If neither of these settings is suitable, the user may '''manually''' identify the extraction region using the extraction window sliders below the plot window and clicking '''"Update with Manual Settings"''' to apply the changes. To return back to auto extraction, simply select the '''Auto''' radio button. Note: there may be a small delay after adjusting any of these, since the software is recalculating the extracted spectrum and updating all the plot windows in real-time.
Similarly, the side bands used to identify the sky may be tweaked interactively. The regions are not allowed to cross the extraction region, nor to fall outside of the cyan slit boundary. If one of the regions is contaminated by another object, it may be deselected using the check box below the band.
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 disable. The arc extraction simply uses ZZZ
