[MSNoise] msnoise overlap parameter

Hi all, I am new to msnoise and would appreciate a small enlightment: According to the documentation, the "overlap" parameter in the config menu seems to refer to overlapping between the raw seismic signal data windows (duration 30 min by default). However, later in the processing (cf paper), during the CCF comparison with reference, it is said that the ref and current CCFs are sliced in several overlapping windows. My question is, what is the parameter controling this last overlap ? Can it be changed ? (I did not manage to identify it in the doc) Thanks a lot, Best, Thomas
