2 years ago thanks we need to chat about formats to store these new models in. This can only be next week though.
I suggest the Tigger Sky LSM format

Enable the pipeline to use primary beam models when predicting model visibilities. This will allow it to use an intrinsic sky model for calibrator fields, which can then be modified by the appropriate primary beam model to produce different apparent sky models for MeerKAT and SKA dishes.
This cannot be properly tested or merged until we have an appropriate intrinsic sky model for the calibrator fields. The currently used models are all apparent sky models (for MeerKAT antennas)

Enable the pipeline to use primary beam models when predicting model visibilities. This will allow it to use an intrinsic sky model for calibrator fields, which can then be modified by the appropriate primary beam model to produce different apparent sky models for MeerKAT and SKA dishes.
This cannot be properly tested or merged until we have an appropriate intrinsic sky model for the calibrator fields. The currently used models are all apparent sky models (for MeerKAT antennas)
