Physics object corrections for Run 2

CMS Open data group

Data recorded in 2016 and published in 2024

Supplementaries Correction CMS CERN-LHC


Description

CMS supports corrections for various physics objects, either to improve modeling of data by simulation, or to correct for imperfect detector response. For Run 2 data, the official corrections are stored in a common JSON format that can be read with the correctionlib library.

Use with

Use these corrections with any CMS Run 2 (2016 and onward) proton-proton collision or Monte Carlo datasets.

Characteristics

1 file. 10.0 MiB in total.

System details

Use this software in the CMS Open Data Docker container, beginning with 2016 data. Correctionlib can be installed for use with either C++ or Python.

How can you use these data?

The physics object correction files provided here are intended to be read using the correctionlib software. The correction files are a type of structured json, and correctionlib provides an "evaluate" function to access appropriate values within the json file. The contents of the correction files can be explored on this web summary page. Correctionlib can be installed in the CMS Docker containers or VM images.

To use the correction files, download the file from this record and unpack it in a location that is accessible to your software container or image. Install correctionlib following the instructions at https://cms-nanoaod.github.io/correctionlib/install.html.

For more information about physics object access and the individual corrections, see the CMS Open Data Guide web site.
