Abstract
We calculate NLTE transfer of cyclotron-harmonic radiation in the hot spot of an accreting magnetic white dwarf in the case where the contribution of the accretion column to the observed radiation is negligible. The observed spectra and polarization of cyclotron radiation from a polar with a low accretion rate are found. Based on the theory developed, we interpret the cyclotron emission line spectra of the systems and determine physical conditions in the emission regions of HS 1023+3900 and HS 0922+1333.
