    "abstract": "Physics goals of the STAR Experiment at RHIC in recent (and future) years\ndrive the need to operate the STAR TPC at ever higher luminosities, leading to\nincreased ionization levels in the TPC gas. The resulting ionic space charge\nintroduces field distortions in the detector which impact tracking performance.\nFurther complications arise from ionic charge leakage into the main TPC volume\nfrom the high gain anode region. STAR has implemented corrections for these\ndistortions based on measures of luminosity, which we present here.\nAdditionally, we highlight a novel approach to applying the corrections on an\nevent-by-event basis applicable in conditions of rapidly varying ionization\nsources.",
