pyarts.arts.math.make_wigner_ready

math.make_wigner_ready(fastest: int = 250, largest: int = 20000000, symbol_size: int = 6) → int

Initialize a Wigner computation block for wigner3j() or wigner6j()

Parameters:

fastest (int, optional) – The size of the fast table (maybe unused), defaults to 250
largest (int, optional) – The largest symbol combination, defaults to 20000000
symbol_size (int, optional) – The symbol for which the largest symbol and fastest symbol is selected (3 or 6), defaults to 6

Returns:

actual_size – The actual state as returned by the library

Return type:

int
