CCR dive logs for APD

[Willem Ferguson]

Hallo Miika,

I started a discussion earlier about catering for APD equipment. The APD 
dive logs are classical CSV files that can import into the existing CCR 
code straight-out without any modification. The headings are:

Dive_time (s)
Depth (m)
Setpoint (bar)
o2 sensor 1 (bar)
o2 sensor 2 (bar)
o2 sensor 3 (bar)
po2_calculated (bar)
..
..
Amb_temp (C)
Deco-ceiling (m)

All these fit straight into our existing structures.

My suggestion is that, if a CSV dive log file has an extension of .apd 
or .APD then it is taken as an APD log.

As I indicated, for APD, there are two independent dive computers that 
are logged simultaneously. In the proprietary APD software, results from 
both computers are displayed for a particular dive. Within Subsurface 
this will not be easy. But we could deal with this situation by treating 
it as two separate dive computers as they physically are during the 
dive. The most painless approach would be to ask the diver whether 
computer 1 or computer 2 should be imported. This implies a dialogue 
panel. If the diver wishes, then both computers could be imported 
sequentially, just as we currently do for multiple computers during the 
same dive. So, before one proceeds, a policy decision is required on how 
to deal with the 2-computer situation. From a diver perspective one 
should by default import both computers. From the perspective of the 
existing code it is probably easier to opt for a sequential type of 
import. This is the only substantial issue. For the rest, the import 
should be almost trivial.

What do you think?
Kind regards,
