Effective collision strengths for Mg VI

Each fine-structure level is assigned an index number in Table 3 of the manuscript ranging from 1 to 23. These index values are reproduced here in Table 5 to depict a particular transition. eg.

Index 1-3 denotes the transition 2s(2)2p(3)4SO(3/2)-2s(2)2p(3)2DO(5/2) The effective collision strengths for each transition are presented in rows for a number of electron temperatures ranging from log(T)=5.0 to log(T)=6.1. A superscript indicates the power of 10 by which the number should be multiplied.
