Color–magnitude diagram of β Pic moving group members (as drawn from Malo et al. 2013; Binks & Jeffries 2014; Riedel et al. 2014) and the LDS 5606 binary system. Unresolved binaries are indicated with squares. For the sample from Riedel et al. (2014), we used their deblended magnitudes without uncertainties (see their Table 5). V-band magnitudes for LDS 5606 are drawn from UCAC4 and NOMAD; we assume an uncertainty of 0.3 magnitudes for these faint stars. Theoretical isochrones from Baraffe et al. (1998) and Siess et al. (2000) are shown for comparison.
