 The difference in the chi square lies within 1. So 4 function doesn't improve the fit too much wrt the 3 functions. The difference in the chi square lies within 1. So 4 function doesn't improve the fit too much wrt the 3 functions.

 +=== Extrapolation ===
 +Using the extrapolation formula {{ :users:danyyl:dijet:form.jpg?nolink |}}I obtained the following results.
 +== Mass of the 1st resonance is 300 GeV, mass of the 2nd is 500 GeV ==
 +Extrapolation for 300 GeV (should be the same as fit). On X axis ''mjj/Mres'', where Mres is the mass of the resonance (300 GeV). On Y axis - ''Events / 10 Gev''.

 +Extrapolation for 400 GeV. On X axis ''mjj/Mres'', where Mres is the mass of the resonance (400 GeV). On Y axis - ''Events / 10 Gev''. Looks not so bad as I expected.

 +Extrapolation for 500 GeV using fit functions for 400 and 600 GeV:{{ :users:danyyl:dijet:500_extrapol_m12res_400_600.jpg?nolink |}}
 +
 +=== Next steps ===
 +  - Automise the code to produce the extrapolation function for mass from 400 to 600 GeV with step of 10 GeV.
 +  - Have a look to the README Javier sent us about how to perform the fit
