iqm.cpc.core.observation.observation_parameters.AVERAGE_RESPONSE_PHASE = Parameter(name='average_response_phase', label='Average phase accumulation of response', unit='rad', data_type=<DataType.FLOAT: 1>, collection_type=<CollectionType.SCALAR: 0>, element_indices=None)

Inverse of the phase of average response signal, assuming 0 phase in probe pulse. The complex signal is rotated in the IQ plane by 2 factors: SINGLE_SHOT_READOUT_PHASE which is deliberately added to the probe pulse, and factors related to the signal travel time in the physical setup (=`AVERAGE_RESPONSE_PHASE`). This value, together with AVERAGE_RESPONSE_G and AVERAGE_RESPONSE_E, is used to convert measured complex signals to probabilities in software by rotating the signals to the real in axis. The rotation angle is the difference of this value and SINGLE_SHOT_READOUT_PHASE. When calibrated correctly, this value equals SINGLE_SHOT_READOUT_PHASE, such that the correct rotation is done by the pulse, and the received complex values do not need to be rotated.
