## Dielectric Screening

The dielectric matrix of Ozone (O_{3}) is computed in WEST by iterative diagonalization, see Fig. 2 of Ref. [02].
The eigenvalues of the symmetrized irreducible polarizability for Ozone (O_{3}) are reported in Fig. 1.
Results were obtained using the program `wstat.x`

of the WEST package.

## Spectral Function

The G_{0}W_{0} spectral function of Ozone (O_{3}) is computed in WEST with full frequency integration.
Results were obtained using the program `wfreq.x`

of the WEST package.
