The atmosphere and architecture of WASP-189 b probed by its CHEOPS phase curve

Open Access

Table A.1

Thresholds above which a correlation between the measured flux and the background level have been detected in the eclipse observations for each of the photometric extraction method.

Photometric extraction method	Threshold value [e⁻]
DRP – aperture of 22.5 pixels	4 10⁶
DRP – aperture of 25 pixels	5 10⁶
DRP – aperture of 30 pixels	4 10⁶
DRP – aperture of 40 pixels	7 10⁶
PIPE – imagettes	–
PIPE – sub-arrays	1 10³

Notes. These values were used to identify and discard photometric data points before the analysis of the light curves. The PIPE imagette photometry has no value because the flux-background correlation could not be detected in the data.
