      Analyze Data

      This is where we do the main Z-path exercise.

      Start uploading your results to OPloT at least 10 minutes before lunch time (around 12:00-12:05).

      First, check that you remember which dataset you are using: it's identified by a number and a letter. If you don't remember, check the name of the zip-file you downloaded and are reading with Hypatia. That will tell you the Group Letter. The Group number is either 3 or 4. If the first name of the team member whose data set you used starts with A-L, you got a set from Group 3. If it starts with N-Z, it's Group 4. If it starts with an "M", datasets S and T are the last ones from Group 3, and dataset A is the first one from Group 4.

      Go to: and choose "Student" at the top.


      Choose "2024" "April" "27" "Vancouver" <your group number, 3 or 4> <your group letter>

      It should then give you an interface to upload your Invariant_Mass.txt file. Navigate to where you stored it, upload it, and don't forget to press "Submit".

      You should then see some histograms you can look at.
