8.2. CoordinateSystemConverter¶

public class CoordinateSystemConverter¶

Used for conversion between the various coordinate systems used in solar physics datasets based on the SDO mission with its 4096 X 4096 pixel images and a pixel based coordinate system used in displaying images in computer science. implemented by the Data Mining Lab at Georgia State University Some code was taken from SunPy a python library and can be found at http://sunpy.org/
