Process data for DRP2D report

I'd like to discuss

• fibre extraction
• Wavelength calibration
• PSF estimation
• b/r/[n] combination

and requests the following:

For fibre extraction, I think we'll neeed figures of

• fibre flats
• fibre flats overlaid with the fibre traces
• residuals of the fibre flats with the (extracted spectra x fibre traces) removed

Then for the arcs

• Raw arcs (Ne, HgAr, Xe)
• Extracted raw arc spectra (i.e. in pixels)
• Extracted lambda-calibrated arc spectra
• Figures showing the wavelength solution plots (and tables of RMSs)
• Evolution of wavelength solutions with time
• Probably need a figure of the DetectorMaps
• Something about continuum estimation, probably a before-and-after 2-D image

For PSF estimation:
A reminder of Neven's work, probably a list of all the components going into the model
(with pictures as appropriate) followed by

• arcs
• arcs with PSFs subtracted
• extracted arcs lines
• extracted residuals (with error bars)

For b/r/[n] extraction I think we need to show

• b1 arcs
• r1 arcs
• combined arcs
