This procedure is a wrapper to skymap_smooth, which creates a smoothed map of some function sampled at discrete points on the sky. This function implements sigma clipping during the smoothing.
This program repeatedly calls skymap_smooth. After each call, data points which deviate from the smooth map value at (x,y) by more than CLIP sigma are labeled as outliers. The procedure repeats, ignoring outliers, until it converges on a set of outliers.
