Thank you Doug - much appreciated :-)
I've uploaded data.csv
<https://octave.1599824.n4.nabble.com/file/t373550/data.csv> . The data
format is as follows (only the first 6 values are relevant):
time, pos1, posErr1, pos2, posErr2, (posErr2 - posErr1), ignore, ignore
should pos1 and pos2 look the same? because no amount of filtering will make them the same.
Is pos1 from your equipment and pos2 the very accurate one?
In the graph I posted, I plotted the following against time:
posErr1 (brown plot)
posErr2 (blue plot)
posErr2 - posErr1 (green plot)
