FHE threshold

Here are the monitoring plots for the LAC, FLE, FHE thresholds and also pedestal values for the last month. I put those plot togethere after the pointed observation on 3C454.3. The pointed observations on 3C454.3 seems to mainly affect the pedestal values of all channels :

• The pointed observations are followed by an increase of the mean pedestal values for LEX8 and HEX8 channels and a decrease of the same quantity for LEX1 and HEX1. Only spread of the pedestal values of LEX8 and HEX8 increased

• LAC thresholds are also affected but the effect is small

• FLE and FHE threshold increased too.
