DQ Summary Columns


The Run number


Number of events looped over


Mean number of total clusters per event. (including noise clusters)


Mean number of noise clusters per event.
Clusters are considered noise if

Where the default threshold is set to 5.

Proc Eff / Proc Ineff

Processing Efficiency

The result is then truncated to two decimal places (as rounding returns 1.00 everywhere). For Proc Ineff, the Proc Eff is subtracted from 1 and the result displayed in scientific notation.


Total number of error banks


Total number of corrupted banks


Total number of missing banks

Charge MPV

Most probable value for charge in clusters (truncated)
Calculated using a histogram with 1 ADC count bin with
Defaults: lowest bin = 15; highest bin = 45
