Density plot showing the effects of the batch effect removal strategy on the SP-C analog-Na+ ionic signal for surfactant-treated (Treated, SF) and in untreated control (Ctrl, C) animals. Empty lines show the normalized estimate of the probability distribution prior to batch correction. Vertical black lines show the mode of the distribution showing the average intensity of the background pixels after correction. Vertical red lines show the estimated threshold to identify background pixels
