Functions 1, 2 and 3 then require four terms on the same line as the
calibration type is specified. These are x1, y1, and x2, y2, where x is the
independent variable and y is the dependant variable which we need to
calibrate.
Below, we will use the example of calibrating a compass. A possible
calibration file might look like:
2
0
20
5 25
which would be adding a 20° offset; obviously (hopefully!) it is unlikely
that you would ever have to apply such a large offset to a compass, but
the large numbers are just to illustrate the functionality below.
Functions 4, 5 and 6 are more complicated. The first line of the file is
the same as for calibrations 1, 2 and 3; after this you create one or more
tables to further calibrate the variate, and these operate on whatever the
output is from the first line. The first way that this can be done is with
one simple table of corrections.
