TCam photo session 20250530

I took the TCam photos for IX and IY mirrors at 8:39 ~ 8:41 this morning. The working time was conflict with the calibration work for ETMX. So, I skipped the photo session for ETMX and ETMY. The previous work is klog33878.

ITMY
For ITMY mirror, I updated the reference positions. I also re-draw the yellow line shown at the k1mon4. For ITMX, we don't need to update the reference positions.

Because of Ushiba-san's work (klog33965), the mirror center should have returned to its original position before Komori-san's height adjustment. So, I restored the reference position of the mirror center to the previous one (before the Komori-san's work). I re-draw the yellow line shown at the k1mon4. If necessary, Uchiyama-san assigns the actual worker and takes the working time on the maintenance day.
