1 1) Feedback HERAFitter beta2 (V. Radescu) 2 ============================ 3 - feedback from users lead to discovery of 2 bugs: 4 RT FAST kfactors were estimated to single point, 5 rather full kinematic phase space leading to wrong error evaluation 6 Missmatch in ABM thresholds 7 => release of bug fixed and put on the website. 8 9 - ongoing developments: a list of ongoing developments is presented. 10 These developments are planned to be included in the next release. 11 12 2) ACOT in QCDNUM (A. Kusina) 13 ================= 14 15 ->COMPARE: ZMSTFUN WITH ACOT-QCDNUM (NLO): and very good agreement 16 (and is cross checked with externall code -- very good agreement) 17 ->Missing NLO quark part for FL is implemented. 18 ->check ACOT internal vs. external for SFs: full NLO -< very good agreement. 19 20 Comparing external and internal codes for FL: 21 there is a glitch only in external, not for internal code 22 (where they work exactly at grid pointsm indicating to the 23 the interpolation glitch. 24 25 26 3) Statistical correlations (K. Nowak) 27 =========================== 28 Addition of the covariance matrix method of evaluating the chisquare and 29 is compared to the nuisance parameter method. 30 The advantage is that statistical correlations can be taken into account. 31 The tests did not check the effect of correlations (errors were treated uncorrelared) 32 33 34 4) Plotting tools (K. Nowak) 35 ================= 36 Improved outputs of the drawing tools: 37 38 - Fit results are now printed to the postscript file by DrawResult 39 - Important minuit messages are printed 40 (helps to extimate reliability of the fit results for inexperienced users) 41 42 43 5) Offset method (W. Slominski) 44 ================ 45 46 there are two ways to deal with the correlations in the offset method: 47 -> single job version (99.9% done) --> it takes ~10min per additional correlations (70 min for 7 errors) 48 -> Multiple jobs version: script driven-> under work
