Light curve of NED02 in r-band (black dots). The dashed lines are the mean levels of the first three (light red) and the last two (dark red) cycles. In this case, we observe low-level variability after the noise correction. For this reason, we cannot confirm without any biases whether the light curve presents periodic-like oscillations or artifacts introduced during the detrending process. Furthermore, as discussed in Subsection 5.3.2, we cannot exclude the possibility of over-subtraction of the signal amplitude, which would prevent us from analyzing the light curve correctly in this filter.
