Kernel2D¶

class astropy.convolution.Kernel2D(model=None, x_size=None, y_size=None, array=None, **kwargs)[source]

Base class for 2D filter kernels.

Parameters
modelFittableModel

Model to be evaluated.

x_sizeodd int, optional

Size in x direction of the kernel array. Default = 8 * width.

y_sizeodd int, optional

Size in y direction of the kernel array. Default = 8 * width.

arrayndarray

Kernel array.

modestr, optional
One of the following discretization modes:
• ‘center’ (default)

Discretize model by taking the value at the center of the bin.

• ‘linear_interp’

Discretize model by performing a bilinear interpolation between the values at the corners of the bin.

• ‘oversample’

Discretize model by taking the average on an oversampled grid.

• ‘integrate’

Discretize model by integrating the model over the bin.

widthnumber

Width of the filter kernel.

factornumber, optional

Factor of oversampling. Default factor = 10.
