Data containers used in ska-sdp-datamodels
ska-sdp-datamodels holds data in python Classes. The bulk data and attributes are usually kept in a xarray.Dataset. For each xarray based class there is an accessor which holds class specific methods and properties.
The structure follows the “Memory Data Models” element of the Processing Functions Module view.
