Notes. For each setup, we provide information related to the cadence, the start time and length of the observations, the rms flux stability within an orbit passage before and after correction, the median duty cycle per satellite orbit, and the duty cycle of orbit passages where data were successfully taken. The duty cycles are determined for the corrected lightcurves. The two studied parts of the Orion II campaign, considered as different epochs, are marked as Orion IIa and Orion IIb (see Sect. 3.3). The different BRITE nano-satellites are BAb (BRITE Austria blue), UBr (UniBRITE red), BTr (BRITE Toronto red), BLb (BRITE Lem blue), and BHr (BRITE Heweliusz red).

(a)

After processing, there is a significant timelength reduction due to strong outliers. The timelength mentioned here is that of the corrected photometry.

(b)

These observations were discarded because of i) the strong irregular temperature variability, and ii) the mismatch between the aperture and the CCD sub-raster.

(c)

These observations were not used, due to the presence of strong charge-transfer-inefficiency (CTI) effects. N/A: Not applicable, since the value was not calculated.
