I use App-BioSemi (https://github.com/labstreaminglayer/App-BioSemi) and selecte the "32, no AUX" option (with "BioSemi-ABC" fro Cap Design). I expected to see 32-channel data but actually see 41-channel data when receiving the data with the pylsl package in Python. Which channels correspond to the actuall EEG channels? From 0 to 31 (in Python)? Or from 1 to 32? Some other channels? And what is the order of the 32 channels same as the one shown below (which I got from https://www.biosemi.com/headcap.htm)?
Fp1
AF3
F7

FC1
FC5
T7 (T3)

Pz
PO3

PO4
P4
P8
CP6
CP2

T8 (T4)

And what are the other 9 channels for?
