Model and parametrization uncertaintiey calculations for the HERAFitter PDF fits — •Oleksii Turkot and Katarzyna Wichmann — Deutches Elektronen-Synchrotron (DESY), Notkestraβe 85, Hamburg 22607

HERAFitter is an open source project for the determination of parton distribution functions using QCD fits. It was developed within the H1 and ZEUS collaborations, employed to obtain the HERAPDF sets and is being used by various HERA, LHC and theory groups. The HERAFitter's drawing package provides experimental uncertainty estimation and plotting. Model and parametrization uncertainty calculation procedure and the corresponding update for the drawing tool have been developed and is presented here. It was implemented in the present HERAFitter's stable release.
