#459 after discussion, I was looking at the raw data and in the electron channels, there are some pulseIds that shouldn't exist. The h5 file contains them so it's not an sed issue but should be figured out and address in the loading step.
This is from the tutorial dataset Gd_W110 filename FLASH1_USER3_stream_2_run44799_file1_20230323T005636.1.h5 filtered to see pulses above 1000
