Table 1: Target levels of Ca XV and their threshold energies (in Ryd).
Table 2: Comparison between present (RM1) and earlier (RM2: Aggarwal 1992) results of effective collision strengths for transitions within the levels of the (1s²2s²2p²) ground configuration of Ca XV. ( $a\pm b\equiv {a}\times {10}^{{\pm }b}$ ).
