Erratum to: Extracting kinetic freeze-out temperature and radial flow velocity from an improved Tsallis distribution (The European Physical Journal A, (2017), 53, 3, (44), 10.1140/epja/i2017-12238-1)

The PHENIX data quoted in this paper should be in the pseudorapidity range |η| < 0.35, but not in the rapidity range |y| < 0.5; and the ALICE data should be in the range |η| < 0.8 for the high–transverse-momentum region and in the range |y| < 0.5 for the low–transverse-momentum region, but not only in the range |y| < 0.5. These corrections do not affect the results of the publication. The authors regret these mistakes and apologize for any inconvenience caused.
