Programmatical access to PdmV analysis prescriptions

🏆 EPR credit available: 1-3 months, to be negotiated.

As CAT we are interested in making doing analysis easier and as least error-prone as possible. Therefore, we want to support the development of API interfaces to access PdmV prescription directly from code, with no need for copy-pasting. Your contribution is crucial and we are open to your ideas (and willing to reward your efforts with EPRs 🏆 of course!)

Tools for cutflow bookkeeping

🏆 EPR credit available, to be negotiated.

Are you interested in automatize analysis optimization using modern tools? As CAT, we will to support the building of workflows in the pythonic HEP ecosystem for applying cuts in histograms and also implement algorithms that find optimal cuts.

If interested, do not esitate to join us! Your contribution will be rewarded with EPRs 🏆!

NanoAOD-tools support

🏆 EPR credit available: 1-3 months, to be negotiated.

Are you interested in maintaining and keeping NanoAOD-tools up-to-date? In CAT we will to accept contributions concerning NanoAOD-tools support at various levels:

maintainance and versioning of the code;
adaptation to python3;
review of correction modules to comply to updated POG recipes and to adopt correctionlib;
provision of documentation.
Even contributing to just one of the items above can be of great importance for CMS community and rewarded with EPRs 🏆!

Analysis examples in RDataFrame and Coffea

🏆 EPR credit available: 1-3 months per contribution, to be negotiated.

Got an analysis you are proud of? Do you want to share it with others, and get recognition (i.e. EPR credit)? Come forward! Within CAT we want to maintain a set of good analysis examples and practices. To this end we ask your contribution to provide analysis examples (and your commitment to maintain them) that are:

Written using modern approaches (e.g., but not limited to, Coffea and RDataFrame).
Maintained over a long (we ask that you promise to maintain them for 1 year at least) period of time.
Well documented.
Tick this three boxes and you will be making a great contribution to CMS 👏, which we will reward with EPR credit 🏆.

How to contrbute? Get in touch! And consider subscribing to the CAT hackathon to dive into it (Get specific in the registration form on what you want to do).

Propagation of non-event-weight systematic uncertainties

🏆 EPR credit available: 1-3 months, to be negotiated.

Are you interested in the development of correction code for the emerging modern analysis tools (Coffea and RDataFrame)? In CAT we aim to support the development of common code for the production and propagation of systematic uncertainties that modify the kinematics of the event. A solution dedicated to JME uncertainties for RDataFrame already exists CMSJMECalculator, and your contribution is needed to:

takeover the maintainance of the tool, as current maintainer will be soon no longer active;
move the current implementation towards correctionlib;
extend this library to cover other uncertainties;
develop a solution to make these libraries available outside RDataFrame.
Even contributing to just one of the items above can be of great importance for CMS community and rewarded with EPRs 🏆!
