class AliHFCorrelationFDsubtraction: public TNamed


 Class for subtracting D-hadron correlations from secondary D from B meson decay from D-hadron correlations of prompt+secondary D mesons
       n.b. requires the evaluation of the fraction of prompt D mesons using the same receipes used for D meson cross-section and RAA in D2H pag
       (-> fprompt obtained from FONLL predictions of prompt and secondary D, prompt and secondary D meson efficiencies and a range of hypotheses for
       RAA(DfromB)/RAA(promptD) (if needed)

 that with our procedure the rel. unc. is variation/distribution, and thus its value is strongly dependent on the baseline: only the absolute unc (->variation) is really meaningful
 Options: if fSystUseRMSfromFlatDistr
 =0 the full spread (->DeltaMax, DeltaMin) of the envelopes is used to define the syst unc,
 =1 (default) DeltaMax/sqrt(3) and DeltaMin/sqrt(3) is used;
 =2: as 1 but then the result is reflected to the range (0,pi), to decrease stat unc;
 =3 as 1 then a smoothing is done (pol0 fit over 3 points), then the result is refelcted; other values not implemented yet (e.g. =2 could be taking the RMS)
 =4 as 1 then a smoothing is done (linear fit over 3 points), then the result is refelcted; other values not implemented yet (e.g. =2 could be taking the RMS)
