# linear_arrays_to_wcs¶

gammapy.utils.wcs.linear_arrays_to_wcs(name_x, name_y, bin_edges_x, bin_edges_y)[source]

Make a 2D linear WCS object from arrays of bin edges.

This method gives the correct answer only for linear X, Y binning. X is identified with WCS axis 1, Y is identified with WCS axis 2.

Parameters: name_x : str name of X coordinate, to be used as ‘CTYPE’ value name_y : str name of Y coordinate, to be used as ‘CTYPE’ value 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 wcs : WCS WCS object describing the bin coordinates
