Spectral Line Selection for HMI: A Comparison of Fe I 6173 and Ni I 6768
A. A. Norton, J. Pietarila Graham, R. K. Ulrich +8
We present a study of two spectral lines, Fe I 6173 Angstroms and Ni I 6768 Angstroms, that were candidates to be used in the Helioseismic and Magnetic Imager (HMI) for observing D…
