Scaler channel description

The GUI used to display scalers rates can be open from the icon in the desktop of computer u6pc5 in data-U6. The GUI includes two pages labeled “s800” and “ratios”. Page “s800” includes all the scaler channels; page “ratios” displays ratio values calculated between several pairs of channels. In addition, the GUI includes a panel showing the time evolution of the live time calculated from the live-to-raw trigger ratio, and the live-to-raw clock ratio. The figure below shows the page “ratios” from the scaler GUI:

Example of scaler rates.

The list below is a direct copy of the scaler description file for the s800. This file maps channel names to channel numbers, and in addition determines the layout.
