The coordConv package provides the following classes and functions. See the main documentation for an overview, example and installation instructions.
Coord: represents a position on the sky, with proper motion and radial velocity; provides easy access to spherical and cartesian position. Coord includes spherical geometry methods angularSeparation, directionTo and offset. ICRSCoordSys FK5CoordSys FK4CoordSys GalCoordSys AppGeoCoordSys AppTopoCoordSys ObsCoordSys: refracted apparent topocentric Site: information about the observatory, current earth orientation data (using the IERS Earth Orientation bulletin if maximum accuracy is wanted) and refraction coefficients. The contents are required for conversions involving apparent coordinates and are ignored otherwise. PVT: an object representing a position, velocity and time. PVTCoord: a Coord with nonzero instantaneous cartesian velocity. appTopoFromAppGeo, appGeoFromAppTopo obsFromAppTopo, appTopoFromObs julianEpochFromTAI and taiFromJulianEpoch besselianEpochFromTAI and taiFromBesselianEpoch lastFromTAI rot2D, polarFromXY and xyFromPolar computeRotationMatrix computes a 3d rotation matrix given an axial vector and amount of rotation sind, cosd, tand, asind, acosd, atand and atan2d wrapPos, wrapCtr and wrapNear distanceFromParallax and parallaxFromDistance hypot (not standard in C++ until C++11)
