convolveImage

lsst.drp.tasks.assemble_chi2_coadd.convolveImage(image: Image, psf: Psf) → Image

Convolve an image with a psf

This methodm and the docstring, is based off the method in SourceDetectionTask.

We convolve the image with a Gaussian approximation to the PSF, because this is separable and therefore fast. It’s technically a correlation rather than a convolution, but since we use a symmetric Gaussian there’s no difference.

Parameters

image:

The image to convovle.

psf:

The PSF to convolve the image with.

Returns

convolved:

The result of convolving image with the psf.
