Notes. Catalogue of known strong variables currently available in the literature, identified at high levels of significance, in descending 2MASS ID with spectral, colour and parallactic distance information.

^(a)

Possible binarity indicated in parenthesis, with J1052 being the only resolved binary (Dupuy et al. 2015).

^(b)

Magnitudes given in MKO instead of 2MASS.

^(c)

Estimated photometric distance.

^(d)

The secondary component of the resolved, nearby binary system Luhman 16AB (L7.5 primary component), with MKO magnitudes obtained from the SpT reference (8).
