Comparative clustering analysis of Ca II 854.2 nm spectral profiles from simulations and observations
Thore E. Moe, Tiago M. D. Pereira, Luc Rouppe van der Voort +4
We aim to compare and contrast the typical shapes of synthetic Ca II 854.2 nm spectra found in Bifrost simulations having different magnetic activity with the spectral shapes found…
Solar Atmospheric Heating Due to Small-scale Events in an Emerging Flux Region
Rahul Yadav, Maria D. Kazachenko, Andrey N. Afanasyev +2
We investigate the thermal, kinematic and magnetic structure of small-scale heating events in an emerging flux region (EFR). We use high-resolution multi-line observations (includi…
Shape-based clustering of synthetic Stokes profiles using k-means and k-Shape
Thore Espedal Moe, Tiago M. D. Pereira, Flavio Calvo +1
The shapes of Stokes profiles contain much information about the atmospheric conditions that produced them. However, a variety of different atmospheric structures can produce very…
Designing wavelength sampling for Fabry-Pérot observations. Information-based spectral sampling
C. J. Díaz Baso, L. Rouppe van der Voort, J. de la Cruz Rodríguez +1
Fabry-Pérot interferometers (FPIs) have become very popular in solar observations because they offer a balance between cadence, spatial resolution, and spectral resolution through…
