We present near infrared high-precision photometry for eight transiting hotJupiters observed during their predicted secondary eclipses. Our observationswere carried out using the staring mode of the WIRCam instrument on theCanada-France-Hawaii Telescope (CFHT). We present the observing strategies anddata reduction methods which delivered time series photometry with statisticalphotometric precisionas low as 0.11%. We performed a Bayesian analysis to modelthe eclipse parameters and systematics simultaneously. The measuredplanet-to-star flux ratios allowed us to constrain the thermal emission fromthe day side of these hot Jupiters, as we derived the planet brightnesstemperatures. Our results combined with previously observed eclipses reveal anexcess in the brightness temperatures relative to the blackbody prediction forthe equilibrium temperatures of the planets for a wide range of heatredistribution factors. We find a trend that this excess appears to be largerfor planets with lower equilibrium temperatures. This may imply some additionalsources of radiation, such as reflected light from the host star and/or thermalemission from residual internal heat from the formation of the planet.
