CAL lines in high frequency for the cross-check purpose doesn't seem to be enabled.
Attachment shows the comparison plots at calibration lines between DARM and witnesses below 100Hz (Fig.1) and above 100Hz (Fig.2).
Essential calibration lines shown below are enabled. So line tracking can be done in minimum.
- EXTM: 27.650Hz for actuator efficiency
- Px1: 28.670Hz for actuator efficiency
- Px2: 31.530Hz for optical gain and cavity pole
- Px3: 507.890Hz for optical gain and cavity pole
And also, a line for the cross-check between Pcal-X and Pcal-Y are also enabled.
- Py1: 32.790Hz for cross-check between Pcal-X and Pcal-Y
On the other hand, lines for checking HF doesn't seem to be enabled. Roughly 1-2hrs integration to see them on DARM. So it's difficult to see on the quick check. But now they are not seen also on RxPD. We need to consider permissions (is this change acceptable), procedures (how to enable them), and a schedule (when they can be enabled), etc.
- Px4: 2002.010Hz
- Px5: 2998.730Hz
