What steps will reproduce the problem?
1. Configure wfrog with a wh1080 station and altitude from GPS.
What is the expected output? What do you see instead?
Relative pressure appears 4-5hPa higher than on nearby reliable barometers.
Removing the abs_pressure fudge factor of 4.5 that was added to wh1080.py in
r810 brings the values back into a sensible range, closely matching expected
values.
Rain is harder to judge, but from the limited data I have the fudge factor of
1.36 just makes an already inaccurate instrument substantially less accurate. I
knew both values were suspect immediately, as their implementation is weird and
doesn't necessarily look well thought out (eg. the *10 and /10 for abs_pressure
directly cancel out, and the rain correction would better be implemented as a
straight *1.36).
What version of the product are you using? On what operating system?
svn r953 is bad, and going back to 0.8.2 works fine.
