Data Acquisition and Processing Policy

The XPS Research Core provides users with flexible options for data handling, processing, and publication credit. Please review the following policy carefully before initiating work at the facility.

Option 1 – User-Processed Data
Users receive raw data and perform their own processing.
Option 2 – Facility-Processed Data
The facility provides both data acquisition and data processing services.
Option 3 – Co-Authorship Model
Users are charged only for the data acquisition time; core staff process the data.
