WignerInit

Workspace.WignerInit(self, fast_wigner_stored_symbols: pyarts.arts.Index | None = None, largest_wigner_symbol_parameter: pyarts.arts.Index | None = None, symbol_type: pyarts.arts.Index | None = None) → None

Initialize the Wigner tables

The default values take about 1 Gb memory.

The static data is kept in an external library and is therefore only available inside ARTS. Nevertheless, this must be set by the application because any default value might be too small or too large for the needs of any one application.
