*SYNC THE X-POINTS TO THE REFERENCE CURVE*
==========================================

Resamples one or more curves so their x-points align with a reference curve, using either a merged or reference-only x-grid. Use this worker whenever downstream operations require all curves to share the same x-axis support (e.g., before averaging, differencing, or correlation).

When to use

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Curves To Be Synced
     - curvestobesynced
     - vector
     - —
     - 
     - One or more XY curves (vector) whose x-points will be resampled to match the target grid; accepts multiple curve objects.
   * - Ref Curve
     - ref_curve
     - vector
     - —
     - 
     - Single reference XY curve (vector) whose x-points define the target grid used for synchronisation.
   * - Type Of Sync
     - typeof_sync
     - scalar
     - merge
     - 
     - Grid-building strategy: 'merge' (default) combines x-points from all curves and the reference; 'reference' uses only the reference curve's x-points.
   * - Extrapolate
     - extrapolate
     - scalar
     - yes
     - 
     - Whether to extrapolate ('yes', default) or clip ('no') curve values when the reference grid extends beyond a source curve's x-range.

     - vector
     - Collection of resampled XY curves sharing the synchronised x-grid derived from the chosen sync type and reference curve.
