Histograms of the cold electron detections by RPC-MIP normalized by the total in situ RPC-MIP acquired spectra for the time periods where (i) the RPC-LAP observed cold electrons (first panel) and where (ii) the RPC-LAP does not observed cold electrons (second panel). All are obtained when the RPC-MIP operated in SDL phased sub-mode. The mean (yellow vertical bar) and the median (green vertical bar) of the ratio are also shown in the two histograms.
