Pearson correlation coefficients, r, and associated p values, p.
| Activity indicator | Inactive RGs | Active RGs |
|---|---|---|
| ΔmNUV | r = −0.121; p = 8.2 × 10−4 | r = 0.258; p = 0.046 |
| SCa II H&K | r = −0.100; p = 1.6 × 10−7 | r = 0.216; p = 5.3 × 10−4 |
| SHα | r = 0.028; p = 0.122 | r = 0.291; p = 1.8 × 10−6 |
| SMg I | r = 0.030; p = 0.108 | r = −0.081; p = 0.204 |
| SFe I | r = −0.010; p = 0.585 | r = −0.158; p = 0.012 |
| SCa II IR | r = −0.104; p = 2.3 × 10−8 | r = 0.216; p = 4.8 × 10−4 |
Notes. r and p were computed for different activity indicators as a function of 
, for both inactive spotless and active spotted RGs.
