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

Figure 10

Sensitivity test to metallicity. The reference fake galaxy has a variable composition: 𝑍=0.004 for stars younger than 5 Gyr, 𝑍=0.002 for older stars. The red dots represent the SFR as recovered using a single metallicity 𝑍=0.004 for all epochs.
