Bonding Assignment

Unfortunately, the electronics and ADC channels do not necessarily correspond to the detector segments with the same number. This is because the detector chip was turned by 90 degrees after the design of the electronics, and later flipped for background illumination. Table 5 shows the connection between chip segments, electronics and ADC channels for the old inboard adapter.

For the new inboard and outboard adapters (and backside illumination), ADC channels and detector segments should correspond to each other. This is not tested yet.

We number the ADC channels as the detector segments, from 1 to 8. In the software (IDL and C++), they will be numbered from 0 to 7. Be a little careful, not everything might be 100 % consistent with this convention.
