        Parameters
        ----------
        center : array-like with shape (2,)
            The center of the survey (degrees). ra/dec, gall/galb, etc.

        size : array-like with shape (2,)
            The length of the edge of the rectangle in degrees

        label : string
            The label to put on the colorbar for this survey

        color : string or array-like with shape (3,)
            The color to use when overlaying the survey footprint. Either a
            string or rgb triplet. Default : 'red'

        coord_in : 'C', 'G', or 'E'
            The coordinate system of the input parameters. 'C' would mean
            input values are in ra,dec. Default : 'C'
