Keyword Arguments:
	dipoles (tuple of str) – The multi-pole codes for the desired basis [`('ED, 'MD')`] n0 (float) – refractive index of the 0 layer (typically vacuum, 1.0) [1.0] n1 (float) – refractive index of the 1 layer [1.0] n2 (float) – refractive index of the emitter layer [1.0] n3 (float) – refractive index of the substrate layer (typically quartz, 1.5) [1.0] d (float) – distance from emitter center to 2-3 layer interface, in nanometers [10.0] s (float) – distance from emitter center to 1-2 layer interface, in nanometers [10.0] l (float) – thickness of n1 layer, in nanometers [0.0] NA (float) – the maximum numerical aperture (normalized angular extent) of the basis functions [1.3] pad_w (bool) – construct basis by padding wavelength values near edges of image [False] trim_w (bool) – trim the basis matrix to the desired image dimensions by wavelength [True] wavelength (ndarray) – 1D array of wavelength mapping values [None] k_count (int) – the image size in the momentum dimension. In open slit case, denotes the resolution of the momentum-space basis functions by referring to the grid edge size. That is, each basis function will be calculated on a `k_count X k_count` sized grid [None] open_slit (bool) – whether observation and corresponding basis should be of wide-angle type (ux_count > 1) [True]
