JSky is a Java library that handles some coordinate manipulations. Its primary focus is sky to image manipulations, such as ["AstroLibWCS"] will perform, but some of its classes are more relevant to purely sky coordinate manipulations.
- The World Coordinates interface and implementation
- The ProperMotion class
- The JPrec precession class
- The Cotr class works with rotation matrices to transform from one system of spherical coordinates to another
- The HMS and DMS classes
