Hi, I have data from a survey with fore/back sight compass and clino. I have detected a Therion bug calculating the average data, comparing with the error loops with Auriga, Visualtopo, Compass and Therion. See the next compare. Example from the data in .th file:

You can see Therion do a wrong fore/back sight compass average calculation. The good data average are: 1 3 236.8 -11.4 3 4 163.2 -32 4 5 1.5 -77.7 5 6 212.65 -17.15 The clino average seems OK. Searching in the mail-list I have found the bug was reported before. I think is not corrected since then. https://www.mail-archive.com/therion@speleo.sk/msg04660.html Regards, Evaristo.
