Table A.1: Geneva data were acquired with the Flemish Mercator Telescope at La Palma, Spain. Our total dataset was scanned for the maximum and minimum magnitudes. Observation dates, number of measurements and total timebases of these maxima and minima are given as well. For AC Her, our observational monitoring data are divided in two major blocks of 8 and 446 days with 4612 days inbetween. Additional data were found in the Geneva database (http://obswww.unige.ch/gcpd/gcpd.html).
