*CONVERT CURVES TO PRESSURE DB RMS*
===================================

Combines two input curves (X-values and Y-values) into a cross-plotted curve, then converts the result to a pressure level expressed in dB RMS (root-mean-square decibels). Use this worker when you need to transform raw pressure time-history or spectral data into a dB RMS pressure representation for NVH or acoustic post-processing.

     - X-axis values of the source curve (e.g., frequency in Hz or time in seconds); if a CurveGroup is supplied, only the first curve is used. Optional when curve data is already paired.
   * - Curve With Y-Values
     - curve_y
     - vector

     - 
     - Y-axis values of the source curve (e.g., raw pressure in Pa or amplitude); cross-plotted against curve_x before the dB RMS conversion. Optional when curve data is already paired.
