For the date-observation, indeed my conclusion came from the summary in the log. Thank you for claryfying this. Good to hear, therion uses fractions here, and 1/12 is perfectly good.
To be clear, therion calculates the fractional year taking into account the day of the month - it just doesn't assign quite equal lengths to every day of the year, but instead puts the start of each month 1/12 of a year apart, and then splits up each 1/12 into 28, 29, 30 or 31 equal pieces. Really it should split the year into 365 or 366 equal pieces.
FYI, I submitted a patch to address this which Stacho has merged, so the next release should calculate this using even sized days (leap years aside): https://github.com/therion/therion/pull/52
However i have seen that it looks like the calculated declination is maybe rounded to full degrees? Or is this just an display thing in aven viewer?
Aven currently only shows a whole number of degrees, which is unhelpful for this sort of thing. It probably ought to show one decimal place.
The next release of Survex will show one decimal place. Cheers, Olly
