Classification of circular polarization Stokes profiles in a sunspot using k-means clustering

Mathew, Shibu K.; Raja Bayanna, A.; Louis, Rohan Eugene

The magnetic and velocity fields in sunspots are highly structured on small spatial scales which are encoded in the Stokes profiles. The Stokes profiles are in turn, derived from a sequence of polarization modulations on the incoming light that are imaged using an analyser-detector combination. Our aim is to identify Stokes profiles in a sunspot w…
