Description

There are several use cases where it would be nice to have an array that captures and estimate of the visibility noise. In general, this is a quantity which can be the size of the data, and real-valued. We may want to support an optional data-like array that contains this information. Some of the file formats support such a quantity to various degrees, so we should think about the best way to handle it for different cases.

Research direction

Start by reviewing the existing data-array structures and the supported file-format handling described in the repository. Determine how an optional, real-valued visibility-noise array should be represented across those formats; done means the design and format-specific behavior are specified and consistently supported.
