Correction no. 13.

I used data after 12th correction (/star/institutions/bnl/fisyak/Histograms/RunXIV12AuAu15Old/RunXIV12AuAu15Old.root) and fitted it with new model FitRL5 which is using 5 LandauZ functions convoluted with Gaussian function. 

Fit works for all rows e.g. for:
                                                                    INNER SECTOR                                                                                                                                                        OUTER SECTOR

Mu for all rows:

                                                              mu Vs sector                                                                                                                                                            X axis: sector, Y axis: row, Z axis: mu

Left plot: We observe the difference between inner and outer sector. Pion peak position is shifted for inner sectors by ~0.024 from zero, and for outer sectors by ~0.013 from zero. 
Right plot: Except difference between innr and outer sectors we obserwe dead rows for sector 7, 20 and 24 (white spots).

I used this fit to apply correction TpcSecRowB.20140101.000013.root (directory: /star/institutions/bnl/kasiap/Calibration/StarDb/Calibrations/tpc/)

Landau widths
Widths for Landau functions for inner and outer sector are taken from Monte Carlo data for MIP pion ( pion from momentum range p=(0.45+-0.05)GeV/c ).

Width(sector). Inner width = 0.0762, outer width =0.0699.
