I have made new segments of the science mode without IPC error glitch. 'K1-GRD_SCIENCE_MODE_NO_IPC_ERROR'
(Available at the systemB /home/detchar/Segments/K1-GRD_SCIENCE_MODE_NO_IPC_ERROR/ )
Using this segment, I have run Omicron and computed glitch rate for O4a. The median value for entire O4a period is ~29/min.
