...Table¹

The Table classes are not described in this paper; the general description in [Gle94] still suffices, moreover the class documentation is generally excellent. See http://www.cv.nrao.edu/aips++/docs/aips/implement/Tables.html.

... data).²

Probably we should introduce the notion of reserved namespaces to prevent clashes with (future) standard columns.

... MeasurementSet.³

In C++ it should now be possible to implement a virtual ScalarColumn<Visibility>, although we haven't done so yet. This would be quite convenient.

... classes⁴

These classes are an improvement of the ``MathFunc'' classes which have existed in the AIPS++ system for quite some time. They were, no doubt, influenced by the discussion in [BN94].

Or SkyView if we create more generalized ``Images''.

Corruption is of use in data simulation.

... this⁸

Typically, the Corrector will be multiply inherited from a VirtualColumnEngine, and will merely attach a copy of itself to the MeasurementSet.
