Abstract
Undisputedly, derivation of theoretical systematic uncertainties is an
inseparable ingredient of any robust analysis dealing with experimental data.
However, it is not uncommon, even for those analyses that use state of the art
methods and tools to suffer from insufficient statistics when it comes to the
simulated datasets used to estimate systematic uncertainties. This practically
limits the power, and sometimes the robustness of the analysis.
In this paper, we present \syscalc, a code which is able to derive weights
for various important theoretical systematic uncertainties, including those
related to the choice of the Parton Distribution Function sets and the various
scale choices. \syscalc\ utilizes the central sample generated events to
estimate the related systematic uncertainties, thus, omitting the need for
generating dedicated systematics datasets, and with only a minimal added cost
in terms of computing resources. In this paper we discuss the working
principles of the code accompanied by various validation plots. We also discuss
the structure of the code followed by a practical guide for how to use the
tool.
