4. Conclusion

Although the orthogonal operator method is known to describe energy levels of complex spectra more accurately (by an order of magnitude) than earlier methods, a similar claim for transition probabilities has yet to be proved. However, the transition probabilities of the present pilot cases Ti III and V IV sustain the comparison with the available experimental data successfully. Global agreement with the database of Kurucz (1993) has been found, while discrepancies seem to be in favour of the present calculation.

To avoid typing errors, all tables containing transition probabilities are computer processed. The only stage in which data typing by hand occurs is in the input of the energy fitting program. However, due to the low mean error of the fit with orthogonal operators, the levels values are scrutinized almost automatically.

Complete results of the fits of both the odd and even energy system, as well as the corresponding complete transition arrays can be found in our database (anonymous ftp) at ftp://nucleus.phys.uva.nl in the directory pub/orth/ti3.
