Hope you saw my mail to Joshua with images.

Now, this is becoming interesting. Since both computers are reporting on 
the same sensors, any differences in sensor values are likely to be due 
to the internal logic in each computer, which theoretically should be 
very little. The APD dive profiles that I have show minimimal 
differences, BUT there are many small but measurable differences.

So, the options are:
In the APD import, request whether the user wishes results for C1 or C2.
In any case, for each sensor, summarise the mean and maximum differences 
in O2 readings between C1 and C2, making use of the Extra Data tab.

Another APD issue. Since the data are obtained in CSV format, one would 
not like Subsurface to confuse APD data with other CSV data sources. So 
it may make sense to recommend that the CSV data for APD, after it has 
been pasted into a text file, is saved with an extension of .apd   This 
will facilitate it for importing the information into Subsurface. But, 
fundamentally, the CSV mechanism would still be used. Do you have any 
opinion on this?
Kind regards,
