///// Each 2 LTB channels get "married" internally in the board and will then continue
///// on as 1 LTB channel, visible to the outside. The information about which end of 
///// the Paddle crossed which threshhold is lost.
///// How it works is that the two channels will be combined by the trigger logic:
///// - There are 4 states (2 bits)
/////   - 0 - no hit
/////   - 1 - Hit
/////   - 2 - Beta
/////   - 3 - Veto
///// 
///// Each defining an individual threshold. If that is crossed, the whole paddle
///// (ends A+B) will be read out by the ReadoutBoard
///// 
///// The LTB channels here are labeled 1-8. This is as it is in the TOF spreadsheet.
///// Also dsi is labeled as in the spreadsheet and will start from one.
///// 
///// It is NOT clear from this which ch on the rb is connected to which side, for that
///// the paddle/RB tables need to be consulted.
