data. The naming of the brown dwarfs in Calissendorff et al. 2019 does not follow other works and the companion was called 2M1510B (here from now on: 2M1510D). 2M1510D has a mass of and it is separated by about 4.4 au from 2M1510AB and orbits the eclipsing binary each 30 years. This result was not considered by Triaud et al. 2020 and it could represent a contamination of the eclipsing binary, making a test of the cooling models more challenging.

The orbital period was improved with TESS,
