computePsfImage()

computePsfImage	(		psfModels,
			position,
			useKernelImage = True )

Get a multiband PSF image

The PSF Image or PSF Kernel Image is computed for each band
and combined into a (band, y, x) array.

Parameters
----------
psfModels : `dict[str, lsst.afw.detection.Psf]`
    The list of PSFs in each band.
position : `Point2D` or `tuple`
    Coordinates to evaluate the PSF.
useKernelImage: `bool`
    Execute ``Psf.computeKernelImage`` when ``True`,
    ``PSF/computeImage`` when ``False``.

Returns
-------
psfs: `lsst.afw.image.MultibandImage`
    The multiband PSF image.
