II. Determination Technique and Correlation Relationships Between the K CA II Line Parameters for k1 and k2 Features", "abstract": "We have studied two regions located at the base of a coronal hole. For the K\u2081 intensity minima and K\u2082 peaks, which form between the upper photosphere and the lower chromosphere and in the lower chromosphere respectively, a number of Ca II line parameters have been computed. We have improved the determination technique for \u2206\u03bb\u1d0b\u2081\u1d65 and \u2206\u03bb\u1d0b\u2081\u1d63, \u2206\u03bb\u1d0b\u2082\u1d65 and \u2206\u03bb\u1d0b\u2082\u1d63 line profile shifts, including certain cases when their direct determination was complicated. We have determined I\u1d0b\u2081\u1d65, I\u1d0b\u2081\u1d63, I\u1d0b\u2082\u1d65, I\u1d0b\u2082\u1d63 intensities, K\u2081 minima and K\u2082 peaks separations SEP\u1d0b\u2081 = \u2206\u03bb\u1d0b\u2081\u1d63 \u2013 \u2206\u03bb\u1d0b\u2081\u1d65, SEP\u1d0b\u2082 = \u2206\u03bb\u1d0b\u2082\u1d63 \u2013 \u2206\u03bb\u1d0b\u2082\u1d65, respectively. We have constructed scatter plots and have computed correlation relationships between parameters relating to different levels of atmosphere. We have obtained the following results. The intensities observed in the lower and middle chromosphere are connected closer than intensities related to the upper photosphere and middle chromosphere. The structures with a stronger magnetic field are brighter at the upper photosphere and lower chromosphere levels as compared to the structures with a weaker magnetic field. K\u2081 minima separations are of greater value for the structures with a stronger magnetic field relative to the structures with a weaker magnetic field, whereas K\u2082 peaks separations demonstrate the opposite behavior. They are lower for the structures with a stronger magnetic field. It is true not only for the chosen structures belonging to quiet regions but also for the plage, though we need additional statistics for plages. The relation between shifts of K\u2081 minima and K\u2082 peak intensities for violet and red wings appeared to be weak. This may be due to the considerable contribution of random movements to the velocity field at the upper photosphere and lower chromosphere levels or due to different forming levels for the profile violet and red wings.", "comments": "", "collection": ["astronomy"], "affiliation": ["Institute of Solar-Terrestrial Physics SB RAS, Irkutsk, Russian Federation", "Institute of Solar-Terrestrial Physics SB RAS, Irkutsk, Russian Federation ", "Institute of Solar-Terrestrial Physics SB RAS, Irkutsk, Russian Federation "], "references": [], "publicationDate": "2020-12-00", "urls": [], "authors": ["Turova, Irina", "Grigoryeva, Sofiya", "Ozhogina, Olga"], "keywords": ["photosphere", "chromosphere", "K Ca II line profiles"], "orcid": ["", "", ""]}
