Notes. The term T denotes the time base of the observations, the reciprocal value 1 /T corresponds to the Rayleigh criterion, fNy, is the Nyquist frequency, and DC is the duty cycle. BRITE Lem (BLb) is equipped with a blue filter and observed β Pictoris from December 2016 until June 2017, but due to significantly higher noise in the time series, the data was disregarded from the analysis. See Zwintz et al. (2019) for an analysis of the BLb observations.
