Query: Anisotropic Isometric Fluctuation Relations in experiment and theory on
  a self-propelled rod   The Isometric Fluctuation Relation (IFR) [P.I. Hurtado et al., PNAS 108, 7704
(2011)] relates the relative probability of current fluctuations of fixed
magnitude in different spatial directions. We test its validity in an
experiment on a tapered rod, rendered motile by vertical vibration and immersed
in a sea of spherical beads. We analyse the statistics of the velocity vector
of the rod and show that they depart significantly from the IFR of Hurtado et
al. Aided by a Langevin-equation model we show that our measurements are
largely described by an anisotropic generalization of the IFR [R. Villavicencio
et al., EPL 105, 30009 (2014)], with no fitting parameters, but with a
discrepancy in the prefactor whose origin may lie in the detailed statistics of
the microscopic noise. The experimentally determined Large-Deviation Function
of the velocity vector has a kink on a curve in the plane.
