 > In that output, `min_cw` is the minimum consensus weight of relays that
 we keep in the consensus.  That value would start at the smallest
 consensus weight in the network, and we'd calculate entropy values for all
 relays in the consensus.  Then we'd raise the minimum to the second-
 smallest value in the network, throw out all relays below that value, and
 compute new entropy values.  Continue until we're at the relay with
 highest consensus weight.

 third column, `relays`, contains the number of relays left.  The other
 columns (`all`, `max_all`, etc.) are defined similar to #6232.

 Please review my [https://github.com/gsathya/metrics-
 tasks/compare/bug_1854 bug_1854] branch! Thanks!

 There seems to be quite a bit of relays with "None" bandwidth, should we
 consider such relays?(They count when calculating number of relays but
 don't provide any bandwidth)
