Thank you to whoever wrote the tests, they caught a bug, now fixed. @nvictus I had to add .copy() for the bins, otherwise they were getting modified twice and were getting weird column names... guess this would create extra copies of the bintable in memory? Maybe that's not ideal... thoughts? |

Changed the annotate function to use indexing and concatenation instead of df.merge(). Makes it about 2x faster.
