Example of the isochrone fitting carried out to estimate the stellar mass range that may have been missed by our high-resolution imaging. This color–magnitude diagram corresponds to 2MASS J00322970+6714080, and the plotted isochrone corresponds to an age of 0.9 Gyr. The distance to this object is 10 pc, so here the apparent and absolute magnitudes are identical. However, it should be noted that if the companions are unbound stars at an arbitrary distance, then they may be far from the isochrone that fits the primary in absolute magnitude space. Nonetheless, the fact that the companions are self-consistently compatible with having the same distance as the primary still has informational value. While color uncertainties of the secondary and tertiary components in this system are still large at this point, the placement of these objects on the color–magnitude diagram is consistent with a gravitationally bound triple system.
