Where are the datasets?

Overview

Questions

• Where do I find datasets for data and Monte Carlo?

Objectives

• Be able to find the data and Monte Carlo datasets

CERN Open Data Portal

Our starting point is the landing page for CERN Open Data Portal. You should definitely take some time to explore it. But for now we will select the CMS data.

Find the CMS link under Focus on and click on it.

CMS-specific datasets

The figure below shows the website after we have chosen the CMS data. Note the left-hand sidebar that allows us to filter our selections. Let’s see what’s there.

CERN Open Data Portal - CMS data

The first pass to filter on CMS data

At first glance we can see a few things. First, there is an option to select only Dataset rather than documentation or software or similar materials. Great! Going forward we’ll select Dataset.

Next, scrolling down to see the search options in the left bar, we see that there are a lot of entries for data from 2010, 2011, 2012, 2015, and 2016, the 7 TeV, 8 TeV and 13 TeV running periods. We’ll be working with 2016 data for these exercises.

For the next episode, let’s select Dataset and 2016.

Key Points

• Use the filter selections in the left-hand sidebar of the CERN Open Data Portal to find datasets.
