Star Formation Histories of Dwarf Galaxies from the Colour-Magnitude Diagrams of Their Resolved Stellar Populations

Figure 14

Sensitivity test to differential reddening and line-of-sight spread. Red dots represent the recovered SFH. In (a), the reference fake population is built with a distance spread (𝑚−𝑀)₀=18.9±0.2, while the model used to retrieve the SFH has a single distance (𝑚−𝑀)₀=18.9. In (b), the reference fake population is built with a differential reddening 𝐸(𝐵−𝑉)=0.08±0.04, while the model used to retrieve the SFH has a single reddening 𝐸(𝐵−𝑉)=0.08.
