A recently implemented asymmetric Lanczos algorithm for computing (complex) linear response
functions within the coupled cluster singles (CCS), coupled cluster singles and iterative approximate
doubles (CC2), and coupled cluster singles and doubles (CCSD) is coupled to a Stieltjes
imaging technique in order to describe the photoionization cross section of atoms and molecules,
in the spirit of a similar procedure recently proposed by Averbukh and co-workers within the
Algebraic Diagrammatic Construction approach. Pilot results are reported for the atoms He, Ne,
and Ar and for the molecules H2, H2O, NH3, HF, CO, and CO2
