clip_edges¶
- sunpy.image.coalignment.clip_edges(data, yclips: Unit('pix'), xclips: Unit('pix'))[source]¶
Clips off the “y” and “x” edges of a 2D array according to a list of pixel values. This function is useful for removing data at the edge of 2d images that may be affected by shifts from solar de- rotation and layer co- registration, leaving an image unaffected by edge effects.
- Parameters
data (
numpy.ndarray) – A numpy array of shape(ny, nx).yclips (
astropy.units.Quantity) – The amount to clip in the y-direction of the data. Has units of pixels, and values should be whole non-negative numbers.xclips (
astropy.units.Quantity) – The amount to clip in the x-direction of the data. Has units of pixels, and values should be whole non-negative numbers.
- Returns
numpy.ndarray– A 2D image with edges clipped off according toyclipsandxclipsarrays.
