I had my weekly call with Bonaca (Harvard), about information theory and cold stellar streams. We discussed which streams we should be considering in our paper. We have combinatoric choices, because there are N streams and K Milky-Way parameters; we could constrain any combination of parameters with any combination of streams! And it is even worse than that, because we are talking about basis-function expansions for the Milky-Way potential, which means that K is tending to infinity! We tentatively decided to do something fairly comprehensive and live with the fact that we won't be able to fully interpret it with finite page charges.
