Notes. The magnitude values (Vega magnitudes for the JHKBVR filters; AB magnitudes for the i filter) are not corrected for reddening, the parameters of which are reported in the last column (the AV has been derived from Schlafly & Finkbeiner 2011, for J12270 and from the NH = 5.3 × 1020 cm-2 estimate reported in Campana et al., in prep. for J1023). In the 6th column, the reduced χ2 of the sinusoidal fits of the optical light curves are reported.
