def lat_fixed_formatter(y):
    """Simple minded latitude formatter. 

    Only because those available in cartopy do not leave a blank space
    after the degree symbol so it looks crammed. If used outside this
    module, bear in mind this was thought to be used as part of an
    iterator to later be included in a
    matplotlib.ticker.FixedFormatter call.
    
    Parameters
    ----------
    y: int or float
        Latitude value.

    Returns
    -------
    str with our kind of format. We like that little space after the
    degree symbol. Also notice we are using TeX's degree symbol.
