             Integrand function to integrate. It must take a list of arguments (one for each domain)
             with the same dimension as the grid points used for the corresponding domain and return
             a float (e.g. a function of the form f([x1,y1,z1], [x2,y2,z2]) -> float).
-        integration_chunk_size : int, optional
-            Number of points to integrate at once. This parameter can be used to control the
-            memory usage of the integration. Default is 1000.
         non_vectorized : bool, optional
             Set to True if the integrand is not vectorized. Default is False. If True, the integrand
             will be called for each point of the grid separately without vectorization. This implies
