Detailed Description

template<int N>
class ltl::WCS< N >

Base class for intermediate WCs calculation.

Angles in WCS are deg due to FITS standard requirements. Within CCS angles must be transposed to rad because of libmath. External return methods should deliver again deg. Sorry for the inconvenience, not my fault.
