V-band light curves for CVN16AaAb from ASAS (top panel) and ASAS-SN (lower panel) photometry, with their reported uncertainties. In both plots, the solid line depicts the mean of all plotted values. In the top plot, the dashed line is the mean of the ASAS-SN data, while the dotted line is the mean value of the APASS data (this latter is also shown on the lower panel). In the lower panel, however, the dashed line is the mean value of the ASAS A-quality data. The rms of the ASAS-SN data is clearly much smaller than that of the ASAS survey. Note the different range for the ordinate of the plots, and also that these surveys were not contemporary (different JD zero-points). As can be seen from Table 1, the photometry given in SIMBAD is basically the same as that reported by ASAS, and therefore it was not included in the plot. Additionally, the synthetic V photometry from PD2001 presented in Table 2 is completely wrong, causing it to lie off the scale of these plots (the same is true in the I band; compare i′ to I_PD2010 in that table, see also Section 2.1).
