Analyze Cubes & Kinematics
3KIDNAS
3KIDNAS, the 3D Kinematic Data aNalysis Algorithm for Surveys, fits rotating-disk models to HI cubes and is being used to scale WALLABY kinematic modelling through distributed bootstrap uncertainty runs.
3KIDNAS
WALLABY kinematic-modelling pipeline and distributed bootstrap workflow testbed.
Use Cases
- WALLABY kinematics
- Bootstrap uncertainty fitting
- Distributed HTC workflow testing
- Optical/radio follow-up
Deployment Targets
GitHubCANFAR ARCCANFAR Harbor
The WALLABY HI survey is expected to detect roughly 210,000 galaxies, with about 17,000-38,000 expected to be resolved enough for kinematic modelling. The Distributive Network feature highlights the 3KIDNAS bootstrap uncertainty stage: about 1,000 independent tilted-ring fits per galaxy can be distributed across DCP workers, turning a highly parallel analysis step into an HTC workload.
