Parameters describing a trial result from a grid parallel XEB experiment.

data_collection_id The data collection ID of the experiment.
layer The grid layer specifying the pattern of two-qubit interactions in a layer of two-qubit gates for the circuit used to obtain the trial result.
depth The number of cycles executed. A cycle consists of a layer of single-qubit gates followed by a layer of two-qubit gates.
circuit_index The index of the circuit from which the executed cycles are taken.
