Stack masked images. Parameters ---------- shape : `tuple` Shape of the input and output images. bit_mask_value : `int` Bit mask to flag for "bad" inputs that should not be stacked. mask_threshold_dict : `dict` [`int`: `float`], optional Dictionary of mapping from bit number to threshold for flagging. Only bad bits (in bit_mask_value) which mask fractional weight greater than this threshold will be flagged in the output image. mask_map : `list` [`tuple`], optional Mapping from input image bits to aggregated coadd bits. no_good_pixels_mask : `int`, optional Bit mask to set when there are no good pixels in the stack. If not set then will set coadd masked image 'NO_DATA' bit. calc_error_from_input_variance : `bool`, optional Calculate the error from the input variance? compute_n_image : `bool`, optional Calculate the n_image map as well as stack?

Add an image to the stack. No bit-filtering is performed when adding an image. Parameters ---------- image : `lsst.afw.image.Image` Image to add to the stack. weight : `float` or `np.ndarray`, optional Weight to apply for weighted mean. If an array, must be same size and shape as input image.
