hogbom_clean
(dirty, psf, gamma=0.1, threshold='default', niter='default')[source]¶ Performs Hogbom Clean on the
dirty
image given thepsf
.Parameters: dirty : np.ndarray
float64 dirty image of shape (ny, nx)
psf : np.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 (optional : integer
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)
