background_deviation_box

ccdproc.background_deviation_box(data, bbox)

Determine the background deviation with a box size of bbox. The algorithm steps through the image and calculates the deviation within each box. It returns an array with the pixels in each box filled with the deviation value.

Parameters:

data : ndarray or MaskedArray

Data to measure background deviation

bbox : int

Box size for calculating background deviation

Returns:

background : ndarray or MaskedArray

An array with the measured background deviation in each pixel

Raises:

ValueError

A value error is raised if bbox is less than 1
