  236. \item Chris Langenburgh prepared a "official TOY MC" <- LOL
  237. \item With unfolding of the angles done by him.
  238. \item on the $1^{st}$ of April I showed the results for full sample(10M) in $1GeV$ $q^2$ bins.
  239. \item Now the rest of this stupidity.

  252. \begin{itemize}
  253. \item 10M events(signal+background) were dived in small ntuples to match the number of events in the real data.
  254. \item Each sample is then fitted(to get signal+bck n. of events).
  255. \item Then we calculate background moments from sidenads and signal window.
  256. \item and extract the signal moments by subtracting the background.

  335. \begin{itemize}
  336. \item For comparison I investigated how the fit behaves in the same toys.
  337. \item Started with the folded PDFs.
  338. \item PDF is as follows:
  339. \end{itemize}
  340. \begin{equation}
  341. PDF=sig(m) \times sig(\cos \theta_l , \cos \theta_k, \phi) + bck(m) \times bck(\cos \theta_l , \cos \theta_k, \phi)
  342. \end{equation}
  343. \begin{itemize}
  344. \item For angles in background case second order cheb. polynomials were chosen.
