Description of the parameters and flat prior ranges.
| Parameter |
Range | Description | ||
|---|---|---|---|---|
| Model | Astrophysical | |||
| Isochrone parameters | τ | logAge | (6, 8) | Cluster age (log10 yr) |
| ζ | [Fe/H] | 0 | Cluster metallicity (dex) | |
| ϵ | AV | [0, 2] | Dust extinction in V band (mag) | |
| Skewed Cauchy PDF parametersa | s (GBP − GRP) | – | (0.15, 0.9) | Scale parameter determined using GBP − GRP colors |
| s (G − GRP) | – | (0.03, 0.1) | Scale parameter determined using G − GRP colors | |
| a | – | (0.15, 0.9) | Skewness, constant across photometric systems | |
Notes.
The PDF parameter ranges have been determined via maximum likelihood fits of Eq. (A.1) to data and isochrones from studies by Bossini et al. (2019) and Dias et al. (2019). We limit the sample to only include clusters within 500 pc and with ages less than 100 Myr, to guarantee similar CMD conditions compared to the Sco-Cen subgroups.
