Comparing NEA surveys

The vast majority of the known NEAs have been discovered by a small
number of very capable NEA surveys.

A natural question to ask is whether the most efficient surveys discover
similar proportions of the various types of NEAs. Similarly, one can ask whether the differences in discovery efficiency of the NEA types can be meaningfully linked to differences in the hardware and in the observational strategies of the surveys.

We use the discovery statistics available at the MPC to address these
questions.
