wherein keff is an effective wave vector of modulated light, Wx and Wy are components of a rotation vector of the inertial point-source matter-wave atom interferometer gyroscope in a plane orthogonal to the direction of propagation of the modulated light; TR is time between pulses of the modulated light during producing matter-wave interference among gyroscope atoms in the expanding cold atom cloud, and Tex is a total expansion time of the expanding cold atom cloud.
