Comparison of Ne III (or Ne²⁺) effective collision strengths between our work (PW), McLaughlin et al. (2011, M11), and composite data as incorporated in the CHIANTI atomic database v10.0.1 (C-1001) for the selected transitions listed inTable 3. The vertical dashed lines indicate the temperature threshold (T ~ 10⁶ K) below which R-matrix data from McLaughlin & Bell (2000) were used in CHIANTI for transitions within the ground configuration. For other transitions, the DW data from Landi & Bhatia (2005) were used by CHIANTI.
