We model phase-resolved (0.1 phase intervals) cyclotron spectroscopy of three polars (EQ Cet, EF Eri, and MQ Dra). The first two datasets were obtained with IRTF/SpeX, while the Bok 2.3-m was used for MQ Dra. For each object, the data are modeled in two ways. First, a Constant Lambda (CL) code based on the work of Schwope et al. (1990), was fit to the data. CL uses four global parameters to approximate the accretion shock: B, the magnetic field strength, kT, the plasma temperature, Lambda, the "size parameter", and Theta, the viewing angle. While the CL code does a good job
recreating the observed data, Structured Shock codes (SS) offer enhanced insight into the mechanisms at work in these objects, by fully resolving the accretion site and computing the radiative transfer through the plasma. To allow for this more physical setup, we use the Fischer and Beuermann (2001) SS code on each object. This poster will be the first published work to contrast
results from CL and SS codes on a phase-resolved dataset.
