From Tanaka-san:

Add an option to apply the median filter to the photometer method? Line 74-79 in my recent /work/tanaka/processing/synthmag/synthmag.py does that job (well, soft of. I did not deal with wavelength points on the edges). I think it can be an argument like photometer(..., medianFilterWidth=None' by default. When is it not None  (e.g., medianFilterWidth=10), then we apply the running median over +/- 10nm range.
