  In his Comment [arXiv:1501.02126 (2015)] on our recent paper [Phys. Rev.
Lett., v. 113, 254101 (2014)], Pikovsky compares two methods for defining the
"phase" of a stochastic oscillator. We reply to his Comment by showing that
neither method can unambiguously identify a unique system of isochrons, when
multiple oscillations coexist in the same system.
