Table 1: Parameters of the single (m=0) double periodic (m=1) cosine functions and their superposition (m=0/1) fitted to the rotation measure variations in the two rings of NGC 4254 (cf. Fig. 3). Amplitude, phase shift, background offset, and the Theil U coefficient of the quality of fit are given.
Table 2: The intrinsic magnetic field strength of total $B_{\rm {tot}}$ and regular $B_{\rm {reg}}$ components as well as the field regularity in different regions of NGC 4254, denoted in Fig. 5 (top-right). The given uncertainties express random noise in the maps used. The errors, including possible systematic uncertainties due to applied assumptions, can reach 25% of the values obtained. The presented magnetic fields strengths are taken directly from magnetic maps described in Sect. 2.3.
Table 3: The fitted relations between total $B_{\rm {tot}}$ , random $B_{\rm {ran}}$ , and regular $B_{\rm {reg}}$ magnetic field strength, and the field regularity ${B_{{\rm reg}}}/{B_{{\rm ran}}}$ , versus star-formation rate SFR for all regions of NGC 4254 and for different magnetic arms.
Table 4: Observed and modeled depolarization of synchrotron emission in several regions of NGC 4254 due to differential Faraday rotation, Faraday dispersion, and gradients in RM. The regions are marked in Fig. 5b.
Table 5: Modeling of the southern magnetic arm of NGC 4254 by stretching/shearing and compression processes. The radio properties of the N magnetic arm are regarded as the initial conditions for the S magnetic arm (region 3 and 1 in Table 2, respectively). The compression and stretching factors were adjusted so as to yield the observational values (given in italics) of synchrotron emissivity ratio S₂/S₂ or the degree of polarization in the southern arm p₂ (see Sect. 3.4).
Table 6: Contrast ratio in and out of the spiral arms in NGC 4254 in polarized and total synchrotron as well as H I emission. The positions of the inspected five regions are denoted in Fig. 1.
