o_3.wgfa (radiative data)

contains wavelengths, gf and A values of the transitions. The wavelengths are based on the experimental energy levels and should be the best available. Wavelengths calculated from the theoretical energies are of an indeterminate accuracy and their values are presented as negative values of the calculated wavelength.

o_3.splups (electron collision data)

contains the spline fits to the electron collision strengths scaled according the rules formulated by Burgess and Tully (1992). Accurate replication of the temperature averaged collision strength over a wide range of temperatures can be accomplished with the data in this file.

%effective collision strengths (trans. within 2s2.2p2 levels): Burke, V.M., Lennon, D.J., 1994, A&ASS, 103, 273
%effective collision strengths for most of the transitions between 2s2.2p2, 2s.2p3, 2p4 levels: 
     Aggarwal, K.M., ApJSS, 1983, 52, 387 and  Aggarwal, K.M., A&A, 1985, 146, 149
%collision strengths all other transitions: Bhatia, A.K., Kastner, S.O., 1993, ADNDT, 54, 133
%comment: The data for the 2-3 transition were wrong, and have been corrected to the original Lennon & Burke values. Peter Young, 6-Jun-06.
%comment: effective collision strengths are accurate in the temperature range 3.7 < Log T < 5.0
