linear_wcs_to_arrays¶

gammapy.utils.wcs.linear_wcs_to_arrays(wcs, nbins_x, nbins_y)[source]¶

Make a 2D linear binning from a WCS object.

This method gives the correct answer only for linear X, Y binning. The method expects angular quantities in the WCS object. X is identified with WCS axis 1, Y is identified with WCS axis 2. The method needs the number of bins as input, since it is not in the WCS object.

Parameters:	wcs : `WCS` WCS object describing the bin coordinates nbins_x : int number of bins in X coordinate nbins_y : int number of bins in Y coordinate
Returns:	bin_edges_x : `Angle` array with the bin edges for the X coordinate bin_edges_y : `Angle` array with the bin edges for the Y coordinate
