keyword=Helicity ADC pedestal fixed.We changed the pedestal values used by the DAQ to 0 for the three ADC channels reading helicity related value (crate 4, slot 24, channel 32, 33 and 34). These values are used in the online display of the helicity and are back ups to our main way of recording helicity related info. With this new pedestal values, our online display looks better. helcityadc is half helicity 0 and half helicity 1 (16000 on the display).
helcityadc show the number of events for which the recorded helicity is 0 or the helicity is +1 (actually 16000 on the display).
hgateadc shows the number of events for which the helicity is defined (16000) and the number of events for which the helicity is flipping (0).
patternadc shows the number of events for which the quartet is starting (16000) and the number of events for which the quarter is ongoing (0).
PS: before we changed the pedestals to 0, their values were ch32: 473, ch33: 327 and ch34:408.
