[ADVANCED\]UV_FIT [Func1 .. FuncN] /CONTINUUM [Field] /INDEX SpIndex [Frequency] [/OUTPUT [File]] [/QUIET] [/RANGE Min Max TYPE]] [/UVRANGE Min Max [Unit]] [/WIDGET N]

Instruct UV_FIT to fit a Continuum channel derived from the current UV table instead of per-channel values, using the specified spectral index SpIndex and giving flux at the specified Frequency (in MHz, if none given an average frequency is derived from the UV data).

/INDEX can only be used if /CONTINUUM option is present.

Nc is the numbField is the field size to determine the number of channels that can be averaged together. If not specified, it is derived by default like for UV_MAP /CONTINUUM. The additional option /RANGE can be used to specify the range of selected channels.

This option is incompatible with /WIDGET and /SAVE.
