Table 5

Fitted eclipse depths and night fluxes derived directly from the phase curve fitting procedure for each of the three different bandpasses.

Eclipse depth (ppm) Night flux (ppm) Dayside temperature (K) Nightside temperature (K)
CHEOPS 367 ± 17 4796 ± 46
TESS 645 ± 15 4643 ± 26
Spitzer

Notes. The last two columns show the corresponding dayside and nightside brightness temperatures, derived using a PHOENIX model for KELT-9 and the respective bandpass filter functions.
