In this picture, we show another example of a cosmic ray shower event as seen by the Monitoring Program. 

On the left side, a picture of the camera with the active pixels in different colours.  For the active pixels marked with a black dot, the histogram on the right side shows the FADC traces with same colour as the pixel. The size of the signal is observed first to increase and then to decrease as the shower develops propagating down in the atmosphere.  

The FADC analyze the signal in steps of 100 ns (histogram bin size). 

The beginning of the shower is seen also in the adjacent telescope which has field of view slightly overlapping.
