Query: Simulating the Role of Stellar Rotation in the Spectroscopic Effects of
  Differential Limb Magnification   Finite-source effects of gravitationally microlensed stars have been well
discussed in the literature, but the role that stellar rotation plays has been
neglected. A differential magnification map applied to a differentially
Doppler-shifted surface alters the profiles of absorption lines, compromising
their ordinarily symmetric nature. Herein, we assess the degree to which this
finite-source effect of differential limb magnification (DLM), in combination
with stellar rotation, alters spectroscopically derived stellar properties. To
achieve this, we simulated a grid of high-magnification microlensing events
using synthetic spectra. Our analysis shows that rotation of the source
generates differences in the measured equivalent widths of absorption lines
supplementary to DLM alone, but only of the order of a few percent. Using the
wings of H alpha from the same simulated data, we confirmed the result of
Johnson et al. (2010) that DLM alters measurements of effective temperature by
< 100 K for dwarf stars, while showing rotation to bear no additional effect.
