Hi morrowwm,
I have tried your latest github post and am getting the following error:
```
root@n4mrv:/home/bg/weewx_tonga_browse-main# ./tonga_barometer.py
distance to eruption 12056.6 km
arrival at 1642257762 (2022-01-15 09:42:41)
opposite pulse arrival at 1642307533 (2022-01-15 23:32:13)
second time around pulse arrival at 1642382887 (2022-01-16 20:28:06)
select datetime, barometer from archive where datetime > 1642240800 and
datetime < 1642395600 and barometer is not null order by dateTime;
query returned 171 data points
Traceback (most recent call last):
File "./tonga_barometer.py", line 96, in <module>
knots = np.linspace(np.min(tdata), np.max(tdata),

TypeError: 'float' object cannot be interpreted as an integer
```
The earlier version worked correctly and I don't think I have changed
anything. I am using the same copy of weewx.sdb and only changed my
lat/lon.
Much appreciated for your work on this software.
Cheers,
Bob
