Notes. p_01CX , p_02CX , p_01L , p_02L are the initial fractional polarization of the first and second Faraday components in the C–X bands frequency range and L band frequency range; χ_01CX, χ_02CX , χ_01L and χ_02L are the initial polarization angle of the Faraday components within the C–X bands frequency range and L band frequency range; RM_1CX, RM _2CX, RM _1L and RM _2L are the RM of the Faraday components within the C–X bands frequency range and L band frequency range; σ_RM1CX, σ_{RM 2CX}, σ_{RM 1L} and σ_{RM 2L} are the Faraday dispersion values of the Faraday components; ΔRM_1CX, Δ RM _2CX, Δ RM _1L and Δ RM _2L are the RM gradient of the Faraday components. AIC is the Akaike Information Criterion, which is a measure of the relative quality of statistical models for a given set of data. BIC is the Bayesian Information Criterion, which is a criterion for model selection among a finite set of models. The lower the BIC, the better the model. redχ² is the reduced chi-squared test. σ² is the estimated variance, which is the squared deviation of a variable from its mean, how far a set of data are displaced from their mean. All the statistics parameters have been determined within the C–X bands frequency range and the L band frequency range.
