Lightcurves of CM Dra (in units of normalized magnitudes) at the potential planetary transit events, plotted against the phase of CM Dra. The data are shown as squares; the line indicates a smoothing fit of the data.
a) Event at heliocentric Julian date (HJD) 49485.395 observed at OHP.
b) The event centered at HJD 2449505.78, observed at Lick (squares) and Mees (crosses) observatories. The light drop appears about 10 minutes later in the Lick observations; this delay may be caused by noise in the data. The amplitude in the Lick data is 0.001 mag, whereas in the Mees data it is 0.0014 mag.
c) Double dip at HJD 49603.33 and 49603.40.
d) Dip at HJD 49855.62, occurring shortly after a secondary eclipse.
e) A long flat dip observed at HJD 49909.54. This event occured shortly after a primary eclipse that was observed at the begin of this night, and had a duration of 180-240 minutes.
