• cmap (matplotlib colormap) – colormap to use for the image. Default is gray. • extent (array-like) – spatial extent to limit the ﬁgure to, given as xmin, xmax, ymin, ymax. • sfact (int) – Factor by which to reduce the number of pixels plotted. Default is 1 (i.e., all pixels are displayed). • showfig (bool) – Open the ﬁgure window. Default is True. • band (array-like ...
