UV_PREVIEW /FILE

        [ADVANCED\]UV_PREVIEW [Key Value [...]] /FILE FileIn [Drop] [/BROWSE At-
    aper]

    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 tele-
    scopes (NOEMA or ALMA) do not produce useable data in these  ones.  The  de-
    fault  drop is 5% of bandwidth on each side, but can be changed with the op-
    tion Drop value (in %).
