Use Case Examples (users, please contribute to these!)
- heat capacity of pure Au shot at low temperatures in fields up to 9 tesla
  - this demonstrated that heat capacity of Au is not field dependent and follows published data (Martin), which verifies the accuracy of our magnetoresistance correction of the Cernox on the heat capacity chip
  - report from Mohan Neupane (Arnab Banerjee lab, PHYS): Gold lowT HeatCap in field Pk3091.pdf
  - data from the run: gold HC and addenda.zip and the .cal file for puck 3091 that was used: Puck3091.cal
