Did Philae graze a crater rim during its first bounce?

Data collected by ROMAP, the Rosetta Lander Magnetometer and Plasma Monitor onboard Philae, is being used to help reconstruct the trajectory of the lander to its final landing site on Comet 67P/Churyumov-Gerasimenko. As we described in an earlier blog post, magnetic fields can be used for this task because both the lander and the orbiter generate small magnetic fields of their own due to the electronic circuits inside the spacecraft.
