Erratum to: Search for CP violation in the phase space of D0→ π−π+π0 decays with the energy test.

The document is a correction notice for an article published in the Journal of High Energy Physics. The correction identifies an error in figure 4 of the paper, specifically the T-value shown on the plot. The correction states that this error is cosmetic and does not affect any other aspects of the paper. The correction notice includes a corrected version of figure 4. The article appears to be related to the search for CP violation in the phase space of D0 → π− π+ π0 decays with the energy test. [Extracted from the article]
