Atomic data and how they propagate in chemical abundances

V. Luridiana, J. García-Rojas (Instituto Astrofísico de Canarias, Tenerife, Spain)

The workshop Uncertainties in Atomic Data and How they Propagate in Chemical Abundances, held on 20-22 October, 2010, at the Instituto de Astrofísica de Canarias in Tenerife (Spain) has brought together scientists concerned with the completeness and accuracy of atomic data for astrophysical applications, such as atomic physicists, theoretical astrophysicists and observers. The topics covered in the workshop included the evaluation of uncertainties in atomic data, the propagation of such uncertainties in chemical abundances, and the feedback between observations and theoretical calculations.
Communication issues were also discussed, such as how to ensure that atomic data are correctly understood and used and which forum is best for a fluid interaction between the communities involved in the production and use of atomic data. Here, I will briefly report on the discussions held during the workshop and on the initiatives that followed.
