Normalized RMSE for RC_peak in reconstruction parameter space. Data within the blue contours passed the current EARL2 limits. The blue cross marks the local nRMSE minima; the cross in the circle marks the global nRMSE minimum. Panels are shown in order of decreasing exposure. The upper left corner of the 30 s panel was excluded from the nRMSE minimum consideration for reasons of relevance
