Histogram of light curve types for the systems where [OI]λ6300 emission was detected (black striped bins), for those that present a HVC (left panel, shaded gray bins), for those that present a NLVC (right panel, blue), and for those that present a BLVC (right panel, red). The ordinate represents the number of systems that present each light curve type. From left to right, the bins represent systems with spot-like light curves in one or both CoRoT runs; systems with accretion burst-dominated light curves in both CoRoT runs; systems with complex light curves in both CoRoT runs; systems with aperiodic extinction-dominated light curves in both CoRoT runs; and systems that showed an AA Tau-like light curve in one or both CoRoT runs.
