HARPS DRS page
The version 3.0 of the HARPS pipeline (DRS) was installed at the
telescope on December 8th 2006.
The major improvements with respect to the previous version (1.9) are:
- New line list for the wavelength solution.
- Relative flux correction based on stars templates (only for CCF computation, switchable).
- Different PSF fitting for order extraction.
- Bisector computation (available in the data package)
Thanks to the these changes the wavelength solution has an accuracy
of the order of 20cm/s.
