Polar Field Correction for HMI Line-of-Sight Synoptic Data
arXiv:1801.04265
Abstract
This document provides some technical notes on the polar field correction scheme for the HMI synoptic maps and daily updated synchronic frames. It is intended as a reference for the new data products and for some minor updates on our previous scheme for MDI (Sun et al. 2011).
