We used the Wide-field Infra-red Camera on the 3.6-m Canada-France Hawaii Telescope to observe an occultation of the planet by its host star. From the resulting occultation lightcurve we find a planet-to-star contrast ratio in the Ks-band of 0.136±0.014% , in agreement with the value of 0.109±0.027% previously determined. We fit the two Ks-band occultation lightcurves simultaneously with occultation lightcurves in the H-band and the Spitzer 3.6-um and 4.5-um bandpasses, radial velocity data, and transit lightcurves. From this, we revise the system parameters and construct the spectral energy distribution (SED) of the dayside atmosphere. By comparing the SED with atmospheric models, we find that both models with and without a thermal inversion are consistent with the data. We find the planet's orbit to be consistent with circular (e<0.072 at 3 sigma). Description: We observed an occultation of WASP-48b on 2012 Aug 6 through the Ks (8302) filter with the Wide-field Infrared Camera (WIRCam) on the 3.6-m Canada-France Hawaii Telescope (CFHT). The table contains the twelve WASP-48b Ks-band occultation lightcurves shown in figure 3 of the paper. The aperture size and number of companion stars are noted in the first two columns. The data are binned in intervals of 10 minutes.
