Shouldn't 6.1078 (hPa) be converted to Pa directly here instead of converting it in vaporPressure
? I find it more clear than later multiplying by 100.0 and having _pSat
in hPa while vaporPressure
in Pa

Going to use 610.78
and added note
Fix #4951
This will effect both AtragMX and AB.
_pSat
was in hPa, needs to be converted to PaThis will require dll rebuild, so I'm thinking push to 3.10?
The effect on air density is fairly small.
Edit: We could just change all extension calls to use
100 * EGVAR(weather,currentHumidity)
to avoid having to recompile? Effect would be the same.
