IEEE Geoscience and Remote Sensing Magazine - December 2019 - 60

Correction
In Theiler et al. [1] in the June 2019 issue of IEEE Geoscience and Remote
Sensing Magazine, there were errors, introduced in the production process, in
(15), Figures 2 and 3, and Table 2. The corrected items are printed here. We
apologize for these errors and any confusion they may have caused.
