Angular Distortion Data for the U.S. east coast
The dataset contains the angular distortion map for the U.S. east coast based on the vertical land motion map. The file contains a single file, with 4 columns: Column 1: Longitude in deg Column 2: Latitude in deg Column 3: angular distortion Column 4: angular distortion categories. There are 4 angular distortion categories: low-0, medium-1, high-2, and very high-3. These categories are based on the angular distortion values, viz: low (angular distortion<1/3,000), medium (1/3,000 ≤angular distortion<1/1,500), high (1/1,500 ≤angular distortion≤1/500), and very high (angular distortion>1/500).
