My Travis is only failing for Linux GCC 7, GCC 6, GCC 5, GCC 4.9 with error
libs/astronomy/test/coordinate/equatorial_coord.cpp:22:57: error: template argument 1 is invalid RightAscension<double, quantity<bud::plane_angle>> ^libs/astronomy/test/coordinate/equatorial_coord.cpp:23:39: error: template argument 2 is invalid ra(25.0 * bud::degrees);Here is equatorial_cord.cpp

In this project, I have made many headers in a similar fashion but never faced such an issue. I will be grateful for any suggestions.
