We finished software work of tilt sensor. 

Now we can analyze tilt sensor signal with real time digital system of KAGRA

We compared the signal of tilt sensor and optical lever.

Two signals were strongly correlated when we give some periodic motion to MCE mirror.(screenshot picture) 

But without the given motion, It was hard to see any correlation. (PDF file)

We found that there are some noise at low frequency. 

So next monday we will enter the tunnel and fix the some problems related with hardware. (environment, misalignment, scattered light, etc.,)
