• The dark count signal SPD detect per second. The probability of dark cont can be obtained through formula calculation.If @SPD_NUM is larger then one, list them separated by ",".
  

Formula: dark_count_prob = dark_count_rate_ * @TIME_WINDOW_WIDTH * @TIME UNIT

• Is store as dark_count_rate in the fortran code.

example

@DARK_COUNT_RATE
2500.0, 2500.0
