Cross-Calibrating Sunspot Magnetic Field Strength Measurements from the McMath-Pierce Solar Telescope and the Dunn Solar Telescope
Fraser T. Watson, Christian Beck, Matthew J. Penn +3
In this article we describe a recent effort to cross-calibrate data from an infrared detector at the McMath-Pierce Solar Telescope and the Facility InfraRed Spectropolarimeter (FIR…
He I vector magnetic field maps of a sunspot and its superpenumbral fine-structure
T. A. Schad, M. J. Penn, H. Lin +1
Advanced inversions of high-resolution spectropolarimetric observations of the He I triplet at 1083 nm are used to generate unique maps of the chromospheric magnetic field vector a…
Understanding the Fe I Line Measurements Returned by the Helioseismic and Magnetic Imager
Daniel P. Cohen, Serena Criscuoli, Laurel Farris +1
The Helioseismic and Magnetic Imager (HMI) aboard the Solar Dynamics Observatory (SDO) observes the Sun at the Fe I 6173 Å line and returns full-disk maps of line-of-sight (LOS) ob…
