Comparison of amplitudes of the 0.82 d⁻¹ frequency determined in this work (SMEI) and reported by Henry & Smith (2012; APT). The two SMEI datasets were split into two subsets. The first point for each camera is a measurement of the amplitude of the signal while the second point (triangle) is an upper limit. The dashed lines indicate the time span of the two SMEI subsets. When BRITE observed the star in 2015−2018 this frequency was not recovered with a detection limit of ∼1 mmag.
