Extragalactic Magnetism with SOFIA (SALSA Legacy Program). III. First Data Release and On-the-fly Polarization Mapping Characterization*

Abstract: We describe the data processing of the Survey on extragALactic magnetiSm with SOFIA (SALSA Legacy Program). This first data release presents 33% (51.34 hr out of 155.7 hr, including overheads) of the total awarded time from 2020 January to 2021 December. Our observations were performed using the newly implemented on-the-fly mapping (OTFMAP) technique in the polarimetric mode. We present the pipeline steps to obtain homogeneously reduced high-level data products of polarimetric maps of galaxies for use in scien… Show more

“…As a result, the light they emit in infrared wavelengths is polarized, with the polarization direction perpendicular to the mean direction of the magnetic field. Only recently has it been possible to trace extragalactic magnetic fields with this method (e.g.,the recent survey by Lopez-Rodriguez et al 2022).…”

“…The observations were reduced using the same pipeline scheme as described in SALSA III (Lopez-Rodriguez et al 2022a). The final data products contain the Stokes IQU, polarization fraction (P), position angle of polarization (PA), polarized intensity (PI), and their uncertainties, with a pixel scale equal to the detector pixel scale, 6 9, at 154 μm.…”

“…The flux calibration uncertainty is estimated to be 8%. We also included the intrinsic polarization uncertainty of 0.2% and angular uncertainty of 3°of HAWC+ (Harper et al 2018;Lopez-Rodriguez et al 2022a). Note that our analysis is performed with polarization measurements having P/σ P 3, which ensures an uncertainty in the angle of polarization of 9°.6.…”

“…The OTFMAP polarimetric mode has been successfully applied to galaxies such as Centaurus A (Lopez-Rodriguez 2021) and NGC 1097 (Lopez-Rodriguez et al 2021a), as well as the filamentary cloud L1495/B211 (Li et al 2021). The full description of the OTFMAP polarization mode of HAWC+ is described by Lopez-Rodriguez et al (2022a). Here we present a summary of the OTFMAP polarimetric observations and data reduction.…”
