Patches_Found Data Series
Feature identification software will identify a small number of solar active region patches using a line-of-sight magnetogram and an intensity image. This data series contains information for each time step during the SDO mission. It provides geometric mapping info and a bitmap image, pointers to the image data, and a number of keywords computed for the patch.
