Notes.A blank space is given when the observations were not done in a particular filter on any given UTdate.
The magnitudes are in the UKIRT photometric system, measured using an aperture of diameter 2′′ and applying aperture corrections. The values given in parenthesis are the 1-σ internal errors.
From the images presented in Varricatt et al. (2010) observed using UKIRT and UFTI; the data of all other nights were obtained using UKIRT and WFCAM.
