3KIDNAS
3D-KInematic Data aNalysis Algorithm for Surveys
Fit rotating-disk models to HI cubes for WALLABY and other untargeted galaxy surveys.
3KIDNAS fits kinematic models to HI data cubes and estimates uncertainties through bootstrap fitting. The existing WALLABY pipeline is being refined for its v1.1 release, including model-quality flags, scientific validation and automated survey-data processing.

Where it runs
Runtime homes
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.
