The notation X_C seems to be a specific criterion or threshold value related to signal detection theory or a similar context. The value of an evidence variable X can exceed this criterion when either signal or noise is presented, as the evidence variable X represents the observer's perception or measurement, which can vary based on the presence of signal, noise, or both.
