Adding new UVW generation code, updating SDP creator code #20

Closed telegraphic closed 9 months ago

telegraphic commented 9 months ago

This addresses #19, in which UVW coordinates were incorrectly generated.

The fix was to use pyuvdata routines to calculate UVW coordinates, instead of relying on the call to create_visibility in SDP. The create_visibility function seems to really only be designed for simulation, so we need to calculate UVW ourselves and then call the Visibility.contructor().

~~Still todo: Add support for _key_key2 dictionaries to uv5_to_uv, so that metadata is maintained~~

Support added in dcp_uvx_devel
