  text: We study the impact of finite-range physics on the zero-range-model analysis
    of three-body recombination in ultracold atoms. We find that temperature dependence
    of the zero-range parameters can vary from one set of measurements to another
    as it may be driven by the distribution of error bars in the experiment, and not
    by the underlying three-body physics. To study finite-temperature effects in three-body
    recombination beyond the zero-range physics, we introduce and examine a finite-range
    model based upon a hyperspherical formalism. The systematic error discussed in
    this Letter may provide a significant contribution to the error bars of measured
    three-body parameters.
