RAW (unfiltered) 22 string event check
- Studies for monopole filter raised a question that there is events which has small NDOM number (less than 80) but has large (larger than 1000) NPE as in the bottom in this Brian's page
As these events are new to EHE group as we have applied default filter of NDOM80 for last a couple of years, I'm also interested to check these event properties.

22 string Nch Distribution 
The left plot should be compared with Brians plot. |
|
The same plot but now NDOM less than 80 and NPE larger than 1000 cut is applied. Now we have 20 events left.

Channel-wise FADC based NPE vs. Channel-wise ATWD based NPE

Event Displays with the raw waveforms of the largest NPE entry is also shown, such that you can roughly convert ADC count to NPE by eye
|
NDOM is 75, NPE is 1045 
|
|
NDOM is 15, NPE is 1115 
|
|
NDOM is 10, NPE is 1490 
|
|
NDOM is 37, NPE is 1180 
|
|
NDOM is 27, NPE is 1020 
|
|
NDOM is 37, NPE is 1090 
|
One more confirmation, is this conclusion consistent with CORISKA by plots created by Keiichi.
