Having assigned the boundary between sunspots of consecutive solar cycles, we compute COL with sunspots as mentioned above using unsigned latitudes of the sunspots. We count the number of COL in each latitude bin with a bin-size of 1. We subsequently construct a histogram due to COL of sunspots appearing in both hemispheres for a given solar cycle. We then fit the double Gaussian function to the histogram by independently adjusting 6 parameters (two amplitudes, two centroids, and two widths).
