Some options can be set using the `OPTION` directive (in any order)

`OPTIONS` [,`WIGNER`=*value*][,`HLSTRANS`=*value*][,`MATEL`=*value*]

where

`WIGNER`- This option determines whether the Wigner-Eckart theorem should be used when the SO
matrix is determined.
`WIGNER=1`(default) uses the theorem,`WIGNER=0`calculates each SO matrix element individually. This option is needed for test purposes only. `HLSTRANS`- This option determines whether a SO matrix calculation should be performed in the not spin-symmetry adapted
basis set (
`HLSTRANS=0`), in the spin-symmetry adapted basis set (`HLSTRANS=1`, default) or with both basis sets (`HLSTRANS=2`). At present, symmetry adaption can only be performed for triplet states, where the following notation is used to indicate the symmetry adapted spin functions: , . If only singlet and triplet states are considered, the spin-orbit matrix is blocked according to double-group symmetry and the eigenvalues for each each block are printed separately. In all other cases the`HLSTRANS`option is ignored. `MATEL`- If the entire SO matrix is calculated using
`HLSMAT`, the individual matrix elements are normally not shown. When the option`MATEL=1`is given, the individual matrix elements and the contributions of the internal and external configuration classes are printed.
