Calibration example 1
A sample file might look like:
5 0 20 5 25
Table –1 +
0 10
180 -10
360 10
The first line of the file still works the same as before but the result is
then further calibrated from the table. The –1 following the word
table
indicates that the corrections are applied directly to the output
from the initial calibration. Next, the addition sign (+) after the –1
indicates that the corrections in the table are to be added. Then, the
numbers in the left column indicate values of the incoming data, while
the right column indicates the correction to be applied, with Deckman
interpolating for data between the defined values. The table below
indicates the result of this two-stage calibration:
Original data Result of first line Result after table
0 020 28
90 110 108
180 200 192
340 000 010
You can see that Deckman is interpolating for headings between those at
which the corrections are specified and that the calibrations in the table
are applied to the output from the first line of the file rather than the
original input.
It is also possible to calibrate your variate with respect to another variate
in Deckman’s database.
