With projected-CAP (proj_CAP 2) when calculating resonances with B2 block for pyrrole (basis aug-cc-pVDZ+8s6p) , with moderate to large eta values, the roots are not converging with Max Davidson iteration exhausted for both box and voronoi CAP. How to resolve this problem?
Try to use eom_preconv_singles option and use large number of guess vectors (eom_nguess_singles).
