Light curve of the eclipsing system Ac based on all homogenised V band observations at our disposal, and on all BRITE R band and TESS broad band space photometries plotted for the ephemeris (2). We deliberately show the BRITE data for their original ‘setups’, which have different zero levels (see Appendix C for details). We note that the bottom two BRITE light curves have lower amplitudes than the rest. This is caused by the fact that part of the stellar light was captured by pixels in the defective part of the detector. These light curves are not usable for the final light-curve solution but can still be used to make local determinations of the times of minima discussed here.
