Top: distribution of BRITE data of β Cen from four BRITE satellites. Offsets have been applied to separate the light curves. Bottom: a 1-day series of BRITE observations of β Cen. Note groups of data points separated by the satellites’ orbital period of about 100 min (0.07 d). The same offsets have been applied to the blue-filter (BAb + BLb, upper sequence of points) and red-filter (UBr + BTr, lower sequence of points) data.
