CoM, DPC and iDPC#
Measure detector moments, centering, scan-detector rotation and iDPC integration separately from acquisition loading and image presentation. A fast moment reducer does not establish end-to-end iDPC latency or phase parity.
Existing evidence#
Virtual-image validation record: includes retained CoM/DPC/iDPC browser measurements and backend gates.
Cross-backend parity: recorded agreements and unresolved iDPC discrepancies; preserve the original tolerances and detector-bin labels.
Platform measurement ledger: historical timing and provenance.
These shared records are linked rather than duplicated into a new timing claim. There is no new DPC benchmark run in this documentation reorganization.
Implementation and reproduction#
Use the CoM/DPC/iDPC kernel guide for the source map and coordinate conventions, the public API for calls, and the testing guide for available hardware checks. Compare both vector components, rotation conventions and integrated phase; do not substitute a single image similarity score.
