  We present the first application to real data from the BOSS DR12 dataset of
the Extractor procedure to determine the acoustic scale imprinted on Baryonic
Acoustic Oscillations (BAO). We show that, being largely insensitive to the
broadband shape of the Power Spectrum, this procedure requires a lower number
of nuisance parameters than those used by the BOSS collaboration, For
non-reconstructed data our analysis improves the accuracy on the acoustic scale
by about 20 %, while for reconstructed ones we get essentially the same level
of accuracy as the BOSS analysis.
