Abstract
The large amount of radiative data from the Opacity Project is compared with available experimental and theoretical data for the Carbon and the Silicon sequences. Radiative data for the Opacity Project (OP ; see Seaton /1/) has been calculated for all atoms and ions with Z=1-14,16,18,20 and 26. The Carbon sequence data was computed by Luo and Pradhan /2/ and the Silicon sequence was considered by Pradhan /3/. The calculations consist of oscillator strengths and photoionization cross sections for typically a few hundred bound states in each atom or ion. In the present report the OP data is assessed based on other calcualtions, experimental data and self consistency.
