Example of preliminary candidates for short-timescale and suspected periodic variability whose G light curve iscontaminated by two nearby bright stars. Panel a: Gaia G per-CCD phase-folded light curve. Panel b: excerpt of animage in the R band from the MAIA photometer (Raskin et al. 2013); the targeted candidate is encircled in magenta. Panel c: MAIA differential photometry light-curve in R band obtained with ePipe.
