Abstract
AbstractInterpretations of the eclipse Fabry-Perot interferograms obtained by different authors are compared particularly in point of view of velocity measurements. Advantages and disadvantages of the instrumentation consisting of a Fabry-Perot etalon and a narrow band interference filter are discussed when a coronal emission is imposed on steep gradient coronal continuum. A list of optical and near infrared emission coronal lines is analyzed and a recommendation for employment of the Fe XIV (5303Å) and Fe XI (7892Å) is given. An optical sketch of the Fabry-Perot instrumentation is suggested. It allows to select both the instrumental and coronal continuum contributions to get reliable data on the field velocity.
