ALS X laser gliltcher than Y, but that's from the start of O3
Jenne found that some of ALSX related signals goes funny.
I found that there are more spikes/glitches in ALSX laser than ALSY laser (1st attachment, the scale of the plots are set to show center +-1.5%).
However, this was always the case from the start of O3 (2nd attachment). ALSX still looks kind of fishy but we need to study it more.
