New methods of a data quality control for the neutrino telescope ANTARES


Number of registred muons per minute should be stable but at the picture it isn't because of some factors


Main steps of the data processing. Step 1. Separation of all runs on several groups by mean active sectors.


Step 2. Getting rid of "bad" runs.


Ways to carry out step 2: trying to cut off all points which don't reach the fit line with errors.


Ways to carry out step 2: mean active sectors selection


Ways to carry out step 2: results of mean active sectors selection by example of set 2


Failing of mean active sector selection method on example of set 3: one point is still on the graph

Introduction of new distance parameter


How to find an optimal distance parameter?


Result of using distance selection on example of set 3


Set 4: multilines and splitting on subgroups by triggers

=

+


Set 8: multiline formed by only one trigger and time separation


Statistics and conclusions
