Comment to Health check of MCO (28672)

As well as MCI, I measured TFs of MCO for the helth check.
Figure 1 to 7 show the results.

Since current good alignment is slightly far from the OpLev center (normalized value is about 0.6), the yaw TF have slightly low coherence at high frequencies but it's not so problematic.
Also, the TFs are totally different from the reference but they should be fine because MCO had an issue before and current TF shapes are very similar to those of MCI and MCE.
In addition, low frequency coherence is low as well as MCI but it is also not a serious problem.

Before the final check, it is better to perform QPD centering of OpLevs for finalization before vacuum evacuation and better health check.
