Processing History
Two processings of the data set have now been completed:
 * 1) 2006-12: The CCFs generated at this time were faulty due to a failure to properly take into account CRPIX header keywords in the definition of the Wavelength scale. 113 DRS tarballs processed (i.e. All those available on the VSOP archive as at the end of the period), 3 apparent failures.
 * 2) 2007-01: CRPIX bug fix, G-star template used for all stars. 165 DRS tarballs processed (i.e. All those available from the ESO-Archive, all tarballs and DRS-Web pages were uploaded to VSOP server but Wiki pages have not yet been made for the missing targets).

ToDo

 * The code should in the future be improved to allow weighted averages of individual CCFs into the average CCF and confidence in the measured RV.
 * Re-process using more appropriate template for each star
 * Implement a proper uncertainty estimate
