Oh, right. The HD catalog is so old that you get spectral types like G2 or K0 instead of G2V or K0III o_O

Also, why is there a B7V star in this target list?
<raptop>
...it's Regulus
<raptop>
"The star's surface at the equator rotates at about 320 kilometres per second (199 miles per second), or 96.5% of its critical angular velocity for break-up. It is emitting polarized light because of this.[12]"

[Principia] rkunze 3ce89a7 - Fix linker error when compiling with clang 9+ Clang 9 changed the linkage definition for variable templates with const-qualified type (see https://github.com/llvm/llvm-project/commit/bb750689d51d2109b9898b53a4b69d8183ab1f26). This leads to the following linker error in "make test" when compiling with clang versions >= 9: clang++ -c -std=c++1z -stdlib=libc++ -O3 -g -fPIC
