During an internal review of the O4c Analysis-Ready (AR) frames , the CAL group realized that the calibration measurements conducted on Nov. 10 (klog#35540) hadn't worked well (see also JGW-G2617423). These measurements were intended to resume observing mode following the laser trouble. Since an error budget cannot be provided for the period between the resumption of observations and the first weekly maintenance, the CAL group has decided to exclude data in this period from the AR frames.

The period excluded due to this issue is
