Reading UV tables

uv tables are simply read into [rgb]1,0,0IMAGER by magentaREAD UV. The rest frequency to be used to compute the velocity scale is normally found in the table, but can be overridden using the magentaREAD /FREQUENCY option. By default, the whole table is read, but a subset of the channels can be read using the magentaREAD /RANGE option (with the velocity scale as above).

UVFITS file may even be read directly as uv tables, applying the same conversion methods than the violetfits_to_uvt script. However, this capability is still only partially supported. While it will work for basic (i.e. in memory) handling, full access to the uv data is only possible on the native format: this includes subset selection, as well as direct operations on uv data files through the magenta/FILE option of many magentaUV_... commands.
