By Crontab & SCP connection we extract
and archive power supply values every 10 minutes.
The power supply values are shown on three-day Monitor (updated every hour) to check the functionalities of the different power supply systems.

Probability Density Function (PDF)
Evaluation of seismic noise over a long time by PQLX software (*McNamara and Buland, 2004) :
trace statistics, Power Spectral Densities (PSD) and Probability Density Functions (PDF) .
PQLX server writes the results to a MySQL database for quick access
Implementation at INGV-Ancona acquisition center:
PQLX server starts every day by crontab process
Data extraction tools allow to evaluate noise levels and statistics about subset of data (in ex., diurnal and nightly data)
The stationary background noise is characterized by the highest probability of occurrence (mode)
Mode: stable noise model for each station
