<br>
<br>
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.
<br>
<br>
See the next compare.

You can see Therion do a wrong fore/back sight compass average
calculation. The good data average are:
<br>
<br>
1 3 236.8 -11.4
<br>
<br>
3 4 163.2 -32
<br>
<br>
4 5 1.5 -77.7
<br>
<br>
5 6 212.65 -17.15
<br>
<br>
The clino average seems OK.
<br>
<br>
Searching in the mail-list I have found the bug was reported
before. I think is not corrected since then.
