Top three rows: nightly binned photometric time series (top: all data in the V band, middle: zoom to ASH2 and SNO data in the V band, bottom: all data in the R band) and aphase plot to the determined rotation period. Bottom row: periodograms of the different instruments in the V band (left), R band (middle), and the combination of all instruments in each band (right). The periodograms for the analysis on individual instruments are color-coded (blue: ASH2, brown: SNO, red: ASAS, green: ASAS-SN, dark green: MEarth T11, purple:MEarth T12), while the combined periodograms are plotted in black. The solid line represents the combined V -band periodogramand the dashed line the combined R-band periodogram. For the combined periodograms we show the FAP level of 0.001 (green solid line for V band and red dashed line for R band). The vertical black line in each periodogram represents the determined rotation period of 68.4 d and 68.5 d, respectively.
