Gridder: add automatic selection of index type
Currently, we use uint32_t
to store the indices of visibilities we want to grid/degrid. For very large measurement sets, this may not be enough (everything under 1 billion visibilities should be safe though).
It's possible to make Tidx
a template parameter and call code with Tidx=uint64_t
for really large MS without any user interaction. This increases compiled code size a bit, but that should not be a problem.
