ITMY Oplev

Before starting measuring Pitch to Pitch on ITMY, I realized the oplev signal was oscillating at high frequencies. I took a spectra and compared with other oplevs, and the noise floor from 1000Hz is ~2 orders of magnitude higher compared to ITMX. Thomas pointed out that this oplev doesn't have an analog whitening filter yet, so we should double check when it will be installed.

What I meant by "oscillating at higher frequencies" is that the noise is higher for ITMY than ETMX as we can see on the time plots (ETMX in green, ITMY in red)
