FAQ:What are the 'AllStreams' raw data files?

From Daya Bay

Jump to: navigation, search

The DAQ is responsible for combining the data from the trigger board and front-end electronics boards into events. When the DAQ encounters some error with the data structure, it creates an additional 'AllStreams' data file, and put the problematic data into this file. It also issues an error to the DAQ interface, and frequently stops the run. The AllStreams file can be used to understand what caused the DAQ error.

Normal physics analysis should not be done on the AllStreams data files.
