def ev(self, theta, phi, dtheta=<NUM_LIT:0>, dphi=<NUM_LIT:0>):
return self.__call__(theta, phi, dtheta=dtheta, dphi=dphi, grid=False)<EOL>
Evaluate the spline at points

Returns the interpolated value at ``(theta[i], phi[i]),
i=0,...,len(theta)-1``.

Parameters
----------
theta, phi : array-like
    Input coordinates. Standard Numpy broadcasting is obeyed.
dtheta : int
    Order of theta-derivative

    .. versionadded:: 0.14.0
dphi : int
    Order of phi-derivative

    .. versionadded:: 0.14.0
