Masking overlap #271
Description
When the values of the overlap function get too small (e.g. 1e-5), the overlap corrected products explode for the lowest bins.
A simple mask before the overlapCorrection helps to address this:
olFunc355Raman(olFunc355Raman <= 0.01) = NaN;
olFunc532Raman(olFunc532Raman <= 0.01) = NaN;
