cds-question@unistra.fratomic-physicsCollision strengths for transitions among the energetically lowest 46 fine-structure levels belonging to the (1s^2^) 2s^2^2p^2^, 2s2p^3^, 2p^4^, and 2s^2^2p3l configurations of Ca XV are computed, over a wide electron energy range below 300Ryd, using the Dirac Atomic R-matrix Code (DARC) of Norrington & Grant (2003, Comput. Phys. Comm., in preparation). Resonances in the threshold region have been resolved in a fine energy mesh, and excitation rates are determined over a wide electron temperature range below 10^7^K. The results are compared with those available in the literature, and the accuracy of the data is assessed.2003A&A...407..769Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/407/769CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/74 : Atomic Energy Level Data (NIST 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/407/769https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/407/769http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/407/769https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/407/769https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/407/769http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/407/769GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/407/769/table1Target levels of Ca XV and their threshold energies (in Ryd)recnoRecord number assigned by the VizieR team.
