skymap_smooth_sigclip.pro

topskymap_smooth_sigclip

skymap_smooth_sigclip, map, x, y, val, dval, fwhm=fwhm, truncate=truncate, emap=emap, clip=clip, included=included, status=status, verbose=verbose

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.

Parameters

map in required

A map structure, created by map_init.pro

x in required

x location (sky coordinate in degrees) of the data

y in required

y location (sky coordinates in degrees) of the data

val in required

Value of the quantity sampled at (x,y)

dval in required

1-sigma error on val
