[ADVANCED\]UV_PREVIEW [Key Value [...]] /FILE FileIn [Drop] [/BROWSE Ataper]

Without /FILE, UV_PREVIEW works from the current UV data set.

With the /FILE option, it will pre-view the UV data set from the specified file. Edge channels are automatically dropped in this mode, as many telescopes (NOEMA or ALMA) do not produce useable data in these ones. The default drop is 5% of bandwidth on each side, but can be changed with the option Drop value (in %).
