Check behavior of radiometry._interp_common

Lines 900 to 903 in 5f471c0

	# compute a common wavelength array that spans both spectrum and has the
	# desired sampling
	minwave = min(s1.wave.min(), s2.wave.min())
	maxwave = max(s1.wave.max(), s2.wave.max())

I think the intent of _interp_common() is to extract the smallest overlapping region of wavelengths. What is actually happening is that the full extent of wavelengths is being extracted.

Should think about what the right thing to do here is.
