- lock flag
definition : K1:GRD-LSC_LOCK_STATE_N = 1000
- Based on this definition, detchar group provides the segment file in m31-01
- such as /home/detchar/Segments/SegmentList_FPMI_UTC_2019-12-17.txt
- data quality vector
channel name : K1:DET-DQ_STATE_VECTOR
the definition of DQV in full data : definition
- the definition of DQV in ll_merged data is same as full data.
CBC lock segments until 2019/12/18 JST.
We checked lock flag of each data and collected the locked data. We considered lock segments by file units for convenience. If compared with lock segment(DetChar), this lock segment is small slightly.
