Book ChapterDOI
Vector Spectropolarimetry with the Advanced Stokes Polarimeter (ASP) for Quantitative Solar Magnetometry
TL;DR: In this article, the validity of the analytic inversion of Stokes vector profiles of the FeI λ63015 and A63025 A lines to determine vector magnetic fields in the active region NOAA 7197 is shown from several points of view and includes a comparison with direct Zeeman splitting (IR data) and model free geometric methods.
Journal ArticleDOI
Converging Flows in the Penumbra of a δ Sunspot
TL;DR: In this paper, two-component analyses of the observed Stokes spectral profiles in the vicinity of the polarity inversion line were performed in order to extract information about unresolved structure of the magnetic field and its associated flows.
Journal ArticleDOI

TL;DR: In this paper, the penumbral filaments were resolved in spectropolarimetric measurements using inversion codes with only one-component model atmospheres, and thus to assign the obtained stratifications of the plasma parameters directly to the Penumbral fine structure.

TL;DR: In this paper, high-resolution imaging observation of a sunspot umbra was done with Hinode solar optical telescope (SOT) filtergrams in wavelengths of blue and green continuum were taken during three consecutive days.
A suite of community tools for spectro-polarimetric analysis .
TL;DR: The Community Spectro-polarimetric Analysis Center (CSAC) as mentioned in this paper is a community effort to develop tools for extracting the solar magnetic field vector and related atmospheric parameters from spectropolarIMetric observations, and the focus of CSAC is to develop portable, efficient, and well documented procedures for analysis of data from the many new and upcoming observational facilities, both ground and space-based.
