Bias-correction due to colour cut in the RGB selection.
| Metallicity bin | Weight |
|---|---|
| −0.5 < [Fe/H] | 1.03 |
| −1.0 < [Fe/H] < -0.5 | 1.01 |
| −1.5 < [Fe/H] < -1.0 | 1.00 |
| −2.0 < [Fe/H] < -1.5 | 0.99 |
| [Fe/H] < -2.0 | 0.99 |
Notes. The weights calculated from PARSEC simulated stellar populations, to bias-correct the metallicity bias introduced by the 0.5 < GBP,0 — GRP,0 < 1.5 cut. The corresponding PARSEC isochrones are seen in Figure 13. The total mass in metallicity bin −1.5 < [Fe/H] < -1.0 is used as the reference mass, as we are only interested in normalised MDFs and thus their shape only. These weights are multiplied to the MDFs to bias-correct them.
