*REMOVE THERMAL EFFECTS*
========================

Removes thermal softening effects from a dynamic engineering stress-strain curve by referencing a quasi-static baseline curve. The worker resamples both curves over a specified strain range and returns a thermally corrected stress-strain curve suitable for downstream material characterization or calibration.

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Quasi Static Curve
     - quasi_static_curve
     - vector
     - —
     - 
     - Engineering stress-strain curve measured at quasi-static strain rate (vector of [strain, stress] pairs); used as the thermal reference baseline — leave empty only if no quasi-static data is available.
   * - Dynamic Curve
     - dynamic_curve
     - vector
     - —
     - 
     - Engineering stress-strain curve measured at elevated (dynamic) strain rate (vector of [strain, stress] pairs); this is the curve from which thermal effects will be removed.
   * - Digitize Points
     - digitize_points
     - scalar
     - 200
     - 
     - Number of evenly spaced points used to re-digitize both curves before processing; default is 200 — increase for higher strain resolution.
   * - Xmin
     - xmin
     - scalar
     - -1
     - 
     - Lower bound of the strain range over which thermal correction is applied; interpreted as an actual strain value or a percentage depending on Limit Type (default -1 means use curve start).
   * - XMax
     - x_max
     - scalar
     - 1
     - 
     - Upper bound of the strain range over which thermal correction is applied; interpreted as an actual strain value or a percentage depending on Limit Type (default 1 means use curve end).
   * - Limit Type
     - limit_type
     - scalar
     - actual
     - 
     - Controls how Xmin/XMax are interpreted: 'actual' treats them as absolute strain values; 'percent' treats them as percentages of the curve's total strain range (default: 'actual').
   * - Scale
     - scale
     - scalar
     - 1
     - 
     - Multiplicative scale factor applied to the output corrected curve; default is 1.0 (no scaling) — adjust to convert units or normalise stress values.
