[newvars]
This section lists the variable numbers for new variables that have been
added to Deckman as part of upgrades. You should not alter this section
unless you have created a large number of new variables in a previous
version of Deckman yourself, in which case re-assigning variable
numbers in this section can save you having to renumber your own after
an upgrade
[2boattelem]
This section controls the two boat telemetry functionality and should not
be edited
[Averages]
This section controls the averaging for the four averaged variables in
Deckman. The first column is the Deckman identification number for an
averaged value and the second column is the Deckman identification
number for the variable which is being averaged. For example, the line
74 5
specifies that the data for variable 74 (average course) is coming from
variable 5 (course).
[Datalog]
This section controls the variables for time series plots in Deckman. The
columns are:
1. Sequential list of numbers.
2. Deckman identification number for the variable to be plotted.
3. Default upper bound for the plot.
4. Default lower bound for the plot.
Therefore, to allow you to plot VMG in Deckman once it has been
successfully been read in, you must add the line:
38 16 0.0 12.0
