One has to be careful with how polarity is handled between groups as well, and if one is working in integer counts (the ANSIR default) or mV (unclear why anyone would use this as it makes file sizes enormous). The response information published below is in **counts** and seems to fit well in huddle tests. Note that the response is the same for all channels and all units (e.g. there are no bespoke calibrations!), all appear to be sample rate insensitive, and the IGU data has been inverted (multiplied by -1) as described here: [[5Hz Node Polarity Issues>>https://auspass.edu.au/xwiki/bin/view/Data/AusPass%20Data/#HSmartSoloNodePolarityIssues]]
