def calculate_bin_widths(edges):

    Calculate the widths of wavelengths bins given their edges.

    Parameters
    ----------
    edges : array_like
        Sequence of bin edges. Must be 1D and have at least two values.

    Returns
    -------
    widths : ndarray
        Array of bin widths. Will be 1D and have one less value than ``edges``.
