How to remove one (bad) beam from calculations
------------------------------------------------


First look at the raw data to determine which beam is bad.

For instance:

  - the daily email has a plot with 9 pings
  - use ``plot_rawadcp.py`` to look at a ``*.raw`` file

Suppose the bad beam is #2 on the OS75 and this ship has OS150 and OS75.
Then add this block to the bottom of the
``/home/adcp/config/proc_cfg.py`` file:


Code block::

 ## bad beam is 1,2,3,4
 badbeam = dict(
    os75bb = 2,
    os75nb = 2,
   os150bb = None,
   os150nb = None,
 )


Then check the syntax::

  pyflakes3 /home/adcp/config/proc_cfg.py


When you are ready,

- Stop recording
- End cruise
- Kill the UHDAS GUI

- Start the UHDAS GUI
- Start a **NEW CRUISE** name
- Start recording
