---+ DQ Summary Columns

---+++ RunNr
The Run number

---+++ RunDate
The date form the timestamp of the first event in this run


---+++ Events 	
Number of events looped over

---+++ Clusters/evt 	
Mean number of total clusters per event. (including noise clusters)

---+++ #Noise/event
Mean number of noise clusters per event.<br />
Clusters are considered noise if<br />
<latex>\frac{S}{N} < \text{threshold} </latex><br />
Where the default threshold is set to 5 (2009) and 6 (2010).

---+++ Proc Eff / Proc Ineff
Processing Efficiency<br />
<latex>\frac{\text{number of total banks} - \text{number of corrupted banks} - \sum_{Banks}\text{fraction not recovered}}{\text{number of total banks}}</latex><br />

For processing inefficiency, the processing efficiency is subtracted from 1 and the result displayed in scientific notation.
---+++ #ErrorBanks
Total number of error banks

---+++ #Corrupted 	
Total number of corrupted banks

---+++ #Missing 	
Total number of missing banks

---+++ Charge MPV 
Most probable value for charge in clusters (truncated)<br />
Calculated using a histogram with 1 ADC count bin with<br />
Defaults: lowest bin = 15; highest bin = 45
