multi_channel_index_calibration

Hardcoded calibration coefficients for the eight-channel pipettor.

Each function returns a dict keyed by string channel index ("1"–"8") containing slope and offset coefficients used to compute VAEM valve-opening times from requested volumes.

get_multichannel_interpolated_aspirate_flow_coefficients()

Return the interpolated dispense offset coefficients for a multichannel pipettor.
