• health monitoring (battery levels, internal temperature, external temperature and pressure, disk filling rate, time quality etc.)
• configuration management (asynchronous parallel setup performed by OMNI),
• interstation trigger, providing an quick automatic data selection and display based on the triggers of each station (standard windowing approach),
• quick data selection/view based on a simple web based form.

The Kheops station running at Moulis as a test site has been stopped. The MiniSEED data files for 1sps, 20sps and 100sps area vailable online.

A number of earthquakes have been recorded. Below is the vertical seismogram for the main shock in L'Aquila, followed by an earthquake in the Northern Pacific. Note how clear are the long period related to the tides.

The tides were clearly observed and a longer signal shows the typical 14-days modulation :

The quality of the site, the sensor and the digitizer make possible to clearly identify various diurnal and semidiurnal tides on the following spectrum (Equilibrium amplitudes for the tides are taken from Apel, 1987).

Although no large earthquake occurred at small distance, the 40Vpp input together with the large dynamic range would have allow to avoid clipping while still recording very low frequency and low amplitude signal.
