[Therion] Issues with average azimuth calculation and backlino

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
