h1. Highrate trigger design and initial threshold

==20230123 threshold==

Threshold is applied to the height of the waveform:

TS1: CerSum(200mv or 410 adc unit) & ShowerSum(70mv or 143 adc unit); 

TS2: SC_D(20mv or 164 adc unit) & ShowerSum(70mv or 143 adc unit) & SC_B(15mv or 123 adc unit).

TS3: 2 out of these 3 inputs: CerSum(200mv or 410 adc unit), ShowerSum(50mv or 103 adc unit), SC_D(20mv or 164 adc unit);

TS4: ShowerSum(100mv or 205 adc unit)

TS5: SC_B(20mv or 164 adc unit).

TS6: CerA#,CerB#,CerC#,CerD#(15mv or 31 adc unit) for each Cherenkov individual input

TS1: CerSum(35mV or 72adc, 2pe) & ShowerSum(70mV or 143adc, 500MeV electron); 

TS2: SC_D(35mV or 287adc) &  SC_B(35mV or 287adc); 

TS3: SC_D(35mV or 287adc) &  SC_A(31mV or 254adc);

TS4: ShowerSum(140mV or 287adc, 1GeV electron);

     or (70mV or 143adc, 500MeV electron);

     or (15mV or 31adc, half MIP);

    (120mV will keep 95% of 1-GeV electrons)

TS5: N/A.

TS6: CerA#,CerB#,CerC#,CerD#(5mV or 20 adc unit) for each Cherenkov individual input.
