  A Numerical Method for the Visualization of the Fe XIV Emission in the Solar Corona Using Broadband Filters, IOP Publising
  článek v časopise ve Web of Science, Jimp
  Cílem tohoto článku je ukázat, jak lze detekovat emisní čáru třináctkrát ionizovaného železa Fe XIV (530,3 nm) na obrazech pořízených během úplného zatmění Slunce pomocí běžně dostupných barevných fotoaparátů. Toto pojetí je technicky zvládnutelné, neboť Fe XIV je nejjasnější emsiní čárou ve vnitřní koróně a snímače těchto fotoaparátů jsou vybaveny Bayerovým filtrem (čtvercová mřížka, která v poměru 2:1:1 obsahuje zelené, modré a červené filtry o spektrální šířce přibližně 100 nm). Srovnáním s obrazy Fe XIV, které byly během úlného zatmění Slunce pořízeny pomocí úzkopásmových filtrů (0,15 nm), je ukázáno, že procedura představená v tomto článku dává kvalitativně přesné výstupy. Tento přístup sice nemůže nahradit úzkopásmové obrazy Fe XIV z hlediska kvantitativního studia koróny, poskytuje však jednoduchý a dostupný nástroj pro studium morfologie emisí ve sluneční koróně, zejména při teplotě ionzizace Fe XIV (1,8 x 10^6 K).

  ENHANCING CORONAL STRUCTURES WITH THE FOURIER NORMALIZING-RADIAL-GRADED FILTER, Chicago Journals
  článek v časopise ve Web of Science, Jimp
  Images of the corona have a high dynamic range which is excellent for quantitative photometric analysis. To understand the processes governing the solar corona, it is essential to have information about the absolute brightness as well as the underlying structure. However, due to the steep radial gradient of brightness in the images, and to the fact that structures closer to the solar disk have higher contrast than structures further from the disk, human vision cannot view the intricate structure of the corona in such images. The recently developed normalizing-radial-graded filter (NRGF) is an effective way for revealing the coronal structure. In this work, we present a more adaptive filter inspired by the NRGF, which we call the Fourier normalizing-radial-graded filter (FNRGF). It approximates the local average and the local standard deviation by a finite Fourier series. This method enables the enhancement of finer details, especially in regions of lower contrast. We also show how the influence of additive noise is reduced by a modification to the FNRGF. To illustrate the power of the method, the FNRGF is applied to images of emission from coronal forbidden lines observed during the 2010 July 11 total solar eclipse. It is also successfully applied to space-based observations of the low corona in the extreme ultraviolet and to white light coronagraph observations, thus demonstrating the validity of the FNRGF as a new tool that will help the interpretation of the information embedded in most types of coronal images.

  THERMODYNAMICS OF THE SOLAR CORONA AND EVOLUTION OF THE SOLAR MAGNETIC FIELD AS INFERRED FROM THE TOTAL SOLAR ECLIPSE OBSERVATIONS OF 2010 JULY 11, Chicago Journals
  článek v časopise ve Web of Science, Jimp
  We report on the first multi-wavelength coronal observations, taken simultaneously in white light, H alpha 656.3 nm, Fe ix 435.9 nm, Fe x 637.4 nm, Fe xi 789.2 nm, Fe xiii 1074.7 nm, Fe xiv 530.3 nm, and Ni xv 670.2 nm, during the total solar eclipse of 2010 July 11 from the atoll of Tatakoto in French Polynesia. The data enabled temperature differentiations as low as 0.2 x 106 K. The first-ever images of the corona in Fe ix and Ni xv showed that there was very little plasma below 5 x 105 K and above 2.5 x 106 K. The suite of multi-wavelength observations also showed that open field lines have an electron temperature near 1x106 K, while the hottest, 2x106 K, plasma resides in intricate loops forming the bulges of streamers, also known as cavities, as discovered in our previous eclipse observations. The eclipse images also revealed unusual coronal structures, in the form of ripples and streaks, produced by the passage of coronal mass ejections and eruptive prominences prior to totality, which could be identified with distinct temperatures for the first time. These trails were most prominent at 106 K. Simultaneous Fe x 17.4 nm observations from Proba2/SWAP provided the first opportunity to compare Fe x emission at 637.4 nm with its extreme-ultraviolet (EUV) counterpart. This comparison demonstrated the unique diagnostic capabilities of the coronal forbidden lines for exploring the evolution of the coronal magnetic field and the thermodynamics of the coronal plasma, in comparison with their EUV counterparts in the distance range of 1-3R. These diagnostics are currently missing from present space-borne and ground-based observatories.

  In this paper, we describe a registration method based on phase correlation which can align scaled, rotated and shifted images. The algorithm is modified so that it can handle images of various modulation transfer functions, images containing additive and impulse noise, images taken by different optical systems with diffuse light and vignetting. A robust extension of the method to subpixel precision is presented.
