"""Convert an ICRS cartesian vector to an ICRS lsst.geom.SpherePoint
Parameters ---------- vec : `list` of `float` An ICRS catesian vector. defRA : `lsst.geom.Angle` or None The RA to use if the vector is too near a pole; ignored if not near a pole.
Raises ------ RuntimeError If vec too near a pole and defRA is None. """ if abs(vec[0]) < _TinyFloat and abs(vec[1]) < _TinyFloat: if defRA is None: raise RuntimeError("At pole and defRA==None") if vec[2] > 0: decDeg = 90.0 else: decDeg = -90.0 return geom.SpherePoint(defRA, decDeg*geom.degrees) return geom.SpherePoint(lsst.sphgeom.Vector3d(*vec)) |
