Lightcurve obtained from the analysis of 117 frames from WAC Red filter images obtained on 2014 May 17 and 18 (black dots). The red dots correspond to a simulation of the lightcurve, taking in consideration a nucleus shape model (Preusker et al. 2015) with a Lambertian model for the surface, which has an albedo of 0.06, and a ray-tracing technique to compute the total output flux at the S/C position.
