Notes. As mentioned in Sect. 4.2, when an estimate and uncertainty are provided, it corresponds to the median and the 68% confidence interval estimated with the 16th and 84th percentiles of the posterior probability density function. When an upper limit is provided, it corresponds to the 99.7th percentile. (a)All relative fluxes are provided corrected from the contamination factor of the light curve. (b)For the Cos+Gauss and the Gauss+Gauss phase curve models, this table only reports the characteristics of the first and main component of the models: the cosine for the Cos+Gauss model and the first Gaussian function, the one with the largest width, for the Gauss+Gauss model. The characteristics of the second component, Gaussian in both models, are reported in Table 4. (c)We caution the reader that the values provided in this table for May+21 are the opposite of the ones provided in their paper due to the difference in convention used for the phase curve offset (see Sect. 4.1). (d)F21 found variations in the occultation depth measured from the three occultations observed in the IRAC1 channel. The value provided here is the average of these three measurements. We do not find such variability in our data analysis. (e)The Gauss+Gauss phase curve model used for the CHEOPS phase-curve has an additional parameter: the standard deviation (σ0, see Eq. (3)) which quantifies the width of the primary and broadest Gaussian which is estimated at 49 ± 7°.
