Correlations with Magnetic Activity in the Solar Near-Surface Shear Layer. II. Radial Shear
M. Cristina Rabello Soares, Sarbani Basu, Richard S. Bogart +1
Using Helioseismic and Magnetic Imager ring-diagram measurements and building on the rotation-rate inferences presented in Paper I for depths of 1-17 Mm, we examine the propert…

Correlations with Magnetic Activity in the Solar Near-Surface Shear Layer. I. Rotation
M. Cristina Rabello Soares, Sarbani Basu, Richard S. Bogart
We used data from the Helioseismic and Magnetic Imager to determine the rotation rate of the near-surface shear layer and its time variation. We applied the ring-diagram analysis t…

Stray Light Correction for the Helioseismic and Magnetic Imager
A. A. Norton, T. L. Duvall, J. Schou +6
We report a point spread function (PSF) and deconvolution procedure to remove stray light from the Helioseismic and Magnetic Imager (HMI) data. Pre-launch calibration observations,…
