The user interface is being developed further with a more modular approach to simplify the design and enable the real-time data reduction facility. The latter is still under current development.
Also, a more detailed approach to the calibration of the spectropolarimetric data is being made. A more refined model has been developed and is being implemented to measure and derive polarimetric errors which have to be used for the proper and self-consistent data reduction of all four Stokes parameters in spectral lines. A science verification program for the detection of weak linear polarization in spectral lines is planned.
