Examples of image reconstructions for data acquired in the Ca II 8542 Å line with CRISP/SST. The first row displays the best frame of the observations in terms of contrast, both for the wideband (first and third columns) and narrowband channels (second and fourth columns) for two different FoVs. The second, third, and fourth rows show the reconstructed images using torchmfbd, MOMFBD, and the experimental NMF parameterization, respectively. Hyperparameters are slightly tuned for each observation. The contrast displayed in each panel is computed over the entire image.
