V-band light curves from ASAS for BU146 (top panel), HDS2440 (middle panel), and YSC62 (bottom panel). Different quality data from ASAS is depicted with different colors, as indicated. The solid line is the average V-band photometry from the A-quality data. Values from Hipparcos, SIMBAD, APASS, or PD2010 that lie too close to the average were omitted for clarity; only values different from the average of the ASAS A-quality data are plotted, as follows: APASS values with a dotted line and PD2010 with a dashed line (top panel).
