Fort.42: 3D Velocity at Recording Stations
==========================================

This file contains velocity time series output at recording stations as specified in the :doc:`Model Parameter and Periodic Boundary Condition File <../input_files/fort15>`.

        end j loop
    end k loop

Notes
-----

* Output is only available in ASCII format
* Time series data is recorded at specified recording stations
* Velocity components are stored as:
    * REAL(QSTA): x-component of velocity
    * AIMAG(QSTA): y-component of velocity
    * WZSTA: vertical velocity component
* Data is recorded at multiple vertical levels defined by SIGMA values
