IceCube Calibration Workshop 2017

31 Jul 2017, 08:00 → 13 Aug 2017, 18:00 US/Central

Supernova (Madison, WI)

The primary goal of the workshop is to validate/verify the latest ice model (spice 3.2) so that it can be used in new simulation production. We will discuss topics such as the bulk ice, hole ice, DOM efficiency (relative and absolute), SPE corrections, and uncertainties. A second goal of this workshop is to bring together calibration experts and members of other working groups, so that we can better understand how calibration results and uncertainties impact the work of other groups, and work together towards improving implementation and feedback in the future. As such, we strongly encourage collaboration members outside of the calibration working group to attend if they are interested and available!

Friday 4 August

Impact on analysis

• Questions to drive the day's presentations/discussion:
  How can we more effectively/efficiently feed newer ice models into physics analyses?
  If the model error goes from 10% to 5%, does it significantly improve the physics?
• Updates from analyses working on impact of uncertainties (e.g. MultiSim, Tianlu, something from low energy group...)
• Feedback from analyses, e.g. how well is efficiency constrained? Is it consistent among the various analyses?
• Discussion/outline for internal note(s) and/or updated ice model paper(s?); purpose is to provide up-to-date reference for
  uncertainties/correlations/ice model properties
