Correction to: Follow-up timing of 24 pulsars discovered in commensal radio astronomy FAST survey

Le résumé fourni par la source

In the published paper (Q. D. Wu et al. 2023), linear polarization position angles (PAs) and the signs of Faraday rotation measurements were incorrect due to errors in data processing during the polarization calibration process (specifically, the sign flip of Stokes Q was omitted in the data processing). The corrected values of the rotation measure are presented here in Table 2. The integrated polarization profiles and viewing geometry were also corrected, as shown here in Fig. 3, 7, and 8. Since these values are only presented in subsection 3.2, and are not related to other sections, these corrections do not affect the results or conclusions of the published paper. Integrated polarization profiles and viewing geometry of PSRs J1617+1123, J1631+1252, J1900+4221, and J2032+0701. The top panel of each subplot: The black dots with error bars are the PA points. The red line represents the best-fitting RVM model. The PA values of PSR J1617+1123, J1900+4221, and J1631+1252 are |$\ge$| 3 times of the PA errors, respectively. The PA values of PSR J2032+0701 is |$\ge$| 2 times of the PA errors. Bottom panel of each subplot: The total intensity is shown in black, while linearly-polarized flux and circular-polarized flux are shown in red and blue, respectively. Integrated polarization profiles of PSRs J0209+4331, J0211+4235, J0447+2447, J0518+2431, J0540+4542, J0553+4111, J1239+0326, J1611–0114, J1619+3953, and J1836+0915. Integrated polarization profiles of PSRs J1837–0219, J1852–0947, J1854–0036, J1914+2636, J1928–0548, J1938–0940, J2111+2132, J2112+0740, J2159+0202, and J2236+4929. The rotation measure of 24 pulsars. The rotation measure of 24 pulsars. The PSR J1617+1123 has a Faraday rotation measure of 24(1) rad m|$^{-2}$|⁠. We measured the magnetic inclination angle, reference position angle, longitude of the fiducial plane, and viewing angle are |$\alpha =75(3)^{\circ }$|⁠, |$\psi _{0}=-12.8(1)^{\circ }$|⁠, |$\phi _{0}=178.07(1)^{\circ }$|⁠, and |$\zeta =72(3)^{\circ }$|⁠, respectively. We obtained the RM of 30.7(8) rad m|$^{-2}$| for PSR J1631+1252. Through the RVM method, we find |$\psi _{0}=43.8(6)^{\circ }$|⁠, |$\phi _{0}=179.56(6)^{\circ }$|⁠, |$\alpha =49(8)^{\circ }$|⁠, and |$\zeta =52(9)^{\circ }$|⁠. PSR J1900+4221 has a Faraday rotation measure of 19(4) rad m|$^{-2}$|⁠. We find |$\psi _{0}=60.8(2)^{\circ }$|⁠, |$\phi _{0}=174.81(3)^{\circ }$|⁠, |$\alpha =83(2)^{\circ }$|⁠, and |$\zeta =81(2)^{\circ }$|⁠. The RM of PSR J2032+0701 is –96(22) rad m|$^{-2}$|⁠. Through the RVM method, we find |$\psi _{0}=86(6)^{\circ }$|⁠, |$\phi _{0}=183.3(7)^{\circ }$|⁠, |$\alpha =94(4)^{\circ }$|⁠, and |$\zeta =88(4)^{\circ }$|⁠. We thank Glennys Farrar and Michael Unger for bringing this issue to our attention.
