[Therion] Issues with average azimuth calculation and backlino

[Alexandra Shturma]

Hi Staho and Martin,

My name is Sasha and I am one of Abris developers (abris.shturmsoft.com).
Currently, we are working on Therion export and have ran into few issues:

1.       1. Average azimuth calculation is wrong for certain cases. For
example, if we have azimuth=1 and back azimuth = 179, the resulting azimuth
would be 180. However, the resulting azimuth should be 0.

2.       2. Cannot omit backclino with “-”:

data normal from to tape compass backcompass clino backclino

A0 A1 1 100.0 – 0.0 –

Gives an error: -- invalid backwards gradient reading -- -


Best regards,

Sasha Shturma
