The Stieltjes imaging technique is a widely used method to compute the photoionization cross sections,
see e.g. [1,3]. We present results of applying the Stieltjes technique to Lanczos pseudospectra
obtained within Coupled-Cluster response theory [2]. The code for this procedure is to be embedded
within the DALTON software suite.
