◆ cmMedian()

uint16_t sistrip::FEDChannel::cmMedian ( const uint8_t apvIndex ) const

inline

Retrieve the APV CM median for a non-lite zero-suppressed channel

apvIndex should be either 0 or 1 (there are, by construction, two APVs on every channel) No additional checks are done here, so the caller should check the readout mode and/or packet code.
