Magnetically induced spectral line redshifts full disk measurements.
Abstract
The authors describe here a method which will allow the calibration of the magnetically induced velocities and permit an improvement of the information from various planned solar oscillation experiments. Based on the differential sensitivity to the magnetic effects of various spectral lines the authors derive a correction function giving the Doppler shift in each line as a function of the difference between shifts of the lines. For λ5250 the correction to be added to the observed velocity is -0.9±0.1(vλ5237 - vλ5250).
