ith_subgrid_facet_element

ska_sdp_exec_swiftly.fourier_transform.fourier_algorithm.ith_subgrid_facet_element(true_image, offset_i, true_usable_size, mask_element, axis=(0, 1), **kwargs)

Calculate a single facet or subgrid element.

Parameters:

• true_image – true image, G (1D or 2D)

• offset_i – ith offset (subgrid or facet)

• true_usable_size – xA_size for subgrid, and yB_size for facet

• mask_element – an element of subgrid_A or facet_B (masks)

• axis – axis (0, 1, or a tuple of both)

• kwargs – needs to contain the following if dask is used: use_dask: True nout: <number of function outputs> –> 1
