Spatial convolution Moffat filter

2D Moffat filter. This kernel is a typical model for a seeing limited PSF.

Parameters

Raster layer [raster]

Raster layer to be filtered.

Kernel [string]

Python code. See Moffat2DKernel for information on different parameters.

Default:

from astropy.convolution import Moffat2DKernel
kernel = Moffat2DKernel(gamma=2, alpha=2)

Normalize kernel [boolean]

Whether to normalize the kernel to have a sum of one.

Default: False

Interpolate no data pixel [boolean]

Whether to interpolate no data pixel. Will result in renormalization of the kernel at each position ignoring pixels with no data values.

Default: True

Outputs

Output raster layer [rasterDestination]

Raster file destination.
