    Data set for checking a special function.

    Parameters
    ----------
    func : function
        Function to test
    data : numpy array
        columnar data to use for testing
    param_columns : int or tuple of ints
        Columns indices in which the parameters to `func` lie.
        Can be imaginary integers to indicate that the parameter
        should be cast to complex.
    result_columns : int or tuple of ints, optional
        Column indices for expected results from `func`.
    result_func : callable, optional
        Function to call to obtain results.
    rtol : float, optional
        Required relative tolerance. Default is 5*eps.
    atol : float, optional
        Required absolute tolerance. Default is 5*tiny.
    param_filter : function, or tuple of functions/Nones, optional
        Filter functions to exclude some parameter ranges.
        If omitted, no filtering is done.
    knownfailure : str, optional
        Known failure error message to raise when the test is run.
        If omitted, no exception is raised.
    nan_ok : bool, optional
        If nan is always an accepted result.
    vectorized : bool, optional
        Whether all functions passed in are vectorized.
    ignore_inf_sign : bool, optional
        Whether to ignore signs of infinities.
        (Doesn't matter for complex-valued functions.)
    distinguish_nan_and_inf : bool, optional
        If True, treat numbers which contain nans or infs as as
        equal. Sets ignore_inf_sign to be True.
