I prepared the segment file for lockloss of LSC_LOCK guardian. The script generates the segment every 15 minutes.

The segment generated before 9:00 JST is stored in /users/DET/Segments/K1-GRD_LSC_LOCK_LOSS/2024 . The today's segment file (under the update) is stored in /users/DET/tools/Segments/Script/Partial .
