Best-fit parameters for the ṀSED–luminosity relation for each cluster.
| Cluster | Pearson correlation | Intercept (a) | Slope (b) | Difference in intercept (Δai) |
|---|---|---|---|---|
| coefficient | Eq. (4) | Eq. (4) | Eq. (5) | |
| RSGC1 | 0.82 | −32.96 ± 18.43 | 5.03 ± 3.44 | 0 |
| NGC 2100 | 0.85 | −20.15 ± 3.13 | 3.04 ± 0.64 | 2.31 |
| NGC 7419 | 0.99 | −21.24 ± 3.47 | 3.17 ± 0.70 | 1.85 |

Notes. The second column lists the linear Pearson correlation coefficient. The third and fourth column list, respectively, the intercept a and slope b with their standard deviation derived by fitting Eq. (4) to the data. The fifth column lists the fit to Eq. (5) which yields a best-fit slope 
and intercept
