New description:

 Ticket for the tasks related to get sbws in production.
 These would include work we have been already doing, but probably we
 should need to add more tasks:

 1. Get sbws in Debian (#26848)
 2. Check that the bandwidth files results are similar to Torflow:
    We have being doing this in https://github.com/pastly/simple-bw-
 scanner/issues/182, though is growing.
    So far we checked:
   - sbws raw results compared to torflow: shape is quite different
   - sbws raw results compared to sbws scaled: big relays get bigger bw,
 but shape still different from torflow
   - sbws raw results compared to sbws raw results having a bigger time for
 downloading: they're similar
   - sbws raw results compared to sbws raw results resting the rtt from the
 dowload time: they're similar
   - implement parsing Torflow raw files
   - sbws raw results compared to Torflow results: they are similar, so it
 is the scaling method which makes results different
 3. i'd create child tickets for the WIP
     - implement torflow scaling
     - check sbws using torflow scaling compare to Torflow
     - change specification
     - ...
 4. Get one bwauth to run sbws
 5. Archive bw files (#21378)
 6. Compare Tor bw files from bwauths running Torflow and from the one
 running sbws
 7. ...
