Notes. 

(a)

Tycho-2 and IRAS identification, equatorial coordinates from 2MASS, Galactic coordinates and proper motions from Tycho-2; magnitudes and fluxes from catalogues listed in the text; Teff and log g from our SED fits; period and amplitude in the V band from our time-series analysis; and spectral type from our CAFOS observations.

(b)

Tentative periods and amplitudes in parenthesis.
