Notes. ρ and p – the Spearman rank correlation coefficient and its significance. Significant, moderate to strong correlations are highlighted in bold. “a” – for all but B&G spectral type, no statistical results for LC III objects have been provided due to low statistics; “b” – to simplify the analysis, small differences in the Teff range appropriate for LC V/IV and LC II/I objects has been neglected, and an average of the two is only provided.
