Weekly ISI CPS Spectra

All seem to be within spec.

These plots have an updated calibration. Previously, my script had just used a static gain on 1e-9 to get m/rthz, which is wrong. The cps actually need a .14hz pole and 1.4hz zero to be calibrated to nm, with a gain of 3 for the coarse cps and .7 for the fines. Applying this calibration in python has proved more than my meager abilities for now, so I've just applied the gains to get the calibration right above 10 hz, as noted on the plots. I'll try to figure out the rest down the road.
