Description
Solar images obtained in the core of strong chromospheric
lines show fibrils that appear to be tracing the magnetic
field lines. They have been historically used as proxies of
magnetic fields for many purposes. In this work we use a
Bayesian hierarchical model to analyze several tens of
thousands of pixels in spectro-polarimetric chromospheric
images and compare the alignment between the field azimuth
inferred from the linear polarization induced by the Zeeman
effect and the direction of the fibrils in the image.
Fibrils appear to be statistically well aligned with the
magnetic field azimuth.
