## Short Spacings

The task UV_SHORT now supports the mosaic-like UV tables. It can start from a Mosaic UV Table and either a Class Table, or a .lmv datacube as single-dish data. The current implementation offers the following features:

- Maximal backward compatibility: only one new parameter has been added in the .init file of the task to distinguish between the various modes.
- Complete backward capabilities: the new task is also able to process data exactly as previously.
- Minimal interface for the new features: mosaic characteristics are recovered from a mosaic-like UV table, and telescope characteristics from the telescope section of the UV table and Single-dish data if present.
- ability to produce a mosaic-like UV table of the short spacings, with either phase or pointing offsets.
- ability to produce a combined mosaic-like UV table handling both the original mosaic-like UV table and the short spacings derived from the Class table.
- Automatic rescaling of the short spacings weights, but under user control.
- Automatic fall-back on Zero spacings if the single-dish diameter is identical to the diameter of the interferometer antennas.

The .init file has been refurbished, with a re-ordering of parameters so that the (few) mandatory ones appear before the optional ones.
