[Therion] Warning if compass / backcompass differ more than a given threshold

[Roger Schuster]

Hello cavers,

if one uses compass and backcompass in the centreline section Therion
averages both data after inverting the backcompass value. The same is
true for clino and backclino.

Is there a way to give some kind of threshold to the survey data so
Therion issues a warning if compass and (inverted) backcompass differ
too much? Say the threshold is 2 degrees, the value for compass is 90
degrees and the backcompass reading 273 degrees. Now Therion should give
a warning that the difference between both readings is 3 degrees. The
same should be true for clino and backclino readings.

The cherry on top would be if Therion could generate a list of stations
/ legs with differences greater than the threshold. With such kind of
list it would be easy to locate legs which need a re-survey.

Thanks,

Roger
