Data containers used by RASCIL

RASCIL 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.

See rascil.data_models.memory_data_models for the following definitions:

• Image (data and WCS header): rascil.data_models.memory_data_models.Image

• SkyComponent (data for a point source or a Gaussian source): rascil.data_models.memory_data_models.SkyComponent

• SkyModel (collection of SkyComponents and Images): rascil.data_models.memory_data_models.SkyModel

• Baseline-based visibility table, shape (ntimes, nbaselines, nchan, npol), length ntime): rascil.data_models.memory_data_models.Visibility

• Telescope Configuration: rascil.data_models.memory_data_models.Configuration

• GainTable for gain solutions (as e.g. output from solve_gaintable): rascil.data_models.memory_data_models.GainTable

• PointingTable for pointing information: rascil.data_models.memory_data_models.PointingTable

• FlagTable for flagging information: rascil.data_models.memory_data_models.FlagTable
