Deconvolution Algorithms

africanus.deconv.hogbom.hogbom_clean(dirty, psf, gamma=0.1, threshold='default', niter='default')[source]

Performs Hogbom Clean on the dirty image given the psf.

Parameters:

dirtynp.ndarray: float64 dirty image of shape (ny, nx)
psfnp.ndarray: float64 Point Spread Function of shape (2*ny, 2*nx)
gamma (optional) float: the gain factor (must be less than one)
threshold (optional)float or str: the threshold to clean to
niter (optionalinteger: the maximum number of iterations allowed

Returns:

np.ndarray: float64 clean image of shape (ny, nx)
np.ndarray: float64 residual image of shape (ny, nx)
