  We present part 2 of the 6th and final Data Release (DR6 or FDR) of the
Radial Velocity Experiment (RAVE), a magnitude-limited (9<I<12) spectroscopic
survey of Galactic stars randomly selected in the southern hemisphere. The RAVE
medium-resolution spectra (R~7500) cover the Ca-triplet region (8410-8795A) and
span the complete time frame from the start of RAVE observations on 12 April
2003 to their completion on 4 April 2013. In the second of two publications, we
present the data products derived from 518387 observations of 451783 unique
stars using a suite of advanced reduction pipelines focussing on stellar
atmospheric parameters, in particular purely spectroscopically derived stellar
atmospheric parameters (Teff, log(g), and the overall metallicity), enhanced
stellar atmospheric parameters inferred via a Bayesian pipeline using Gaia DR2
astrometric priors, and asteroseismically calibrated stellar atmospheric
parameters for giant stars based on asteroseismic observations for 699 K2
stars. In addition, we provide abundances of the elements Fe, Al, and Ni, as
well as an overall [alpha/Fe] ratio obtained using a new pipeline based on the
GAUGUIN optimization method that is able to deal with variable signal-to-noise
ratios. The RAVE DR6 catalogs are cross matched with relevant astrometric and
photometric catalogs, and are complemented by orbital parameters and effective
temperatures based on the infrared flux method. The data can be accessed via
the RAVE Web site (http://rave-survey.org) or the Vizier database.
