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
