Data products
Under development...
The following is a rough guide to the sorts of data products that are
available. Note that additional facilities might be available for
specialised experiments. Potential observers are encouraged to discuss
their requirements with the KAIRA team to ensure optimal data for their
experiment.
| Data product | Type | Description |
|---|---|---|
| Subband statistics | SST | all 512 subbands, min. 1-second integration |
| Beamlet statistics | BST | upto 244 beamlets, min. 1-second integration |
| Cross correlation statistics | XST | single subband, min. 1-second integration |
| Array covariance cubes | ACC | cross-correlations, stepped subbands, 1s integration only |
| Transient Buffer Board pages | TBB§ | Transient Buffer Board data |
| Transient Buffer Board raw data | § | UDP streamed data |
| Beamlet raw data | ¶ | UDP streamed data |
§ Transient buffer boards are installed at KAIRA, but remain un-tested and without software support them at this stage. If a need arises to implement TBB functionality, please contact the KAIRA PI.
¶ Beamlet raw data can be recorded with a number of different programmes, such as KUW, KLP or KUG. Each has its own data storage format. This is the standard method of recording medium- to high-speed data with KAIRA. KUW data are typically recorded at 100 Hz. KLP and KUG are recorded at raw, maximum data rates.
