smooth

sunkit_image.trace.smooth(image, width, nanopt='replace')

Python implementation of the IDL’s smooth.

Parameters:

• image (numpy.ndarray, sunpy.map.GenericMap) – Image to be filtered.

• width (int) – Width of the boxcar window. The width should always be odd but if even value is given then width + 1 is used as the width of the boxcar.

• nanopt ({"propagate" , "replace"}) – It decides whether to propagate NAN’s or replace them.

Returns:

numpy.ndarray, sunpy.map.GenericMap – Smoothed image. If a map is input, a map is returned with new data and the same metadata.
