1 APODIZE
.ti +4
[WIFISYN\]APODIZE VISICUBE|WIFICUBE /DIRECT|INVERSE /UV|XY
 
Multiply (/DIRECT option) or divide (/INVERSE option) internal complex
buffers (visicube or wificube) by the griding kernels. For the wificube
buffer, the 2D apodization can be applied along either the uv or the xy
planes.
.\"====================================================================

1 COMPLEX
.ti +4
[WIFISYN\]COMPLEX VISICUBE|WIFICUBE TO|FROM AMPLITUDE|PHASE|REAL|IMAGINARY

Transfer complex internal buffers (visicube or wificube) into SIC real
images for display. The inverse operation is possible to set or to modify
the complex internal buffers.
.\"====================================================================
.ti -4
1 FFT
.ti +4
[WIFISYN\]FFT VISICUBE|WIFICUBE /DIRECT|INVERSE /UV|XY
 
Compute the direct or inverse 2D Fast Fourier Transform of internal complex
buffers (visicube or wificube). When the FFT is applied to the wificube
buffer, the 2D FFT can be applied along either the uv or the xy planes.
.\"====================================================================

1 LOAD
.ti +4
[WIFISYN\] LOAD Buffer Varname
 
Load the specified internal buffer (VISI, WEIGHT, BEAM, DIRTY) into the
specified SIC variable (Varname).
.\"====================================================================

1 READ
.ti +4
[WIFISYN\]READ Buffer File [/PLANE First Last]
 
Read the specified internal buffer (UV, BEAM, DIRTY) from the specified
input File. Default extensions are respectively .tuv, .beam, .lmv. A range
of channels can be specified using the /PLANE option.

[WIFISYN\]SETUP

Setup and display the imaging parameters for the internal uvxy table.

1 SHIFT
.ti +4
[WIFISYN\]SHIFT VISICUBE|WIFICUBE /DIRECT|INVERSE /UV|XY
 
SHIFT (/DIRECT option) or UNSHIFT (/INVERSE option) internal complex
buffers (visicube or wificube). Right now, it works only on uv planes of
the wificube buffer. It (un)shifts these uv planes to the varying (x,y)
position.

1 UVMAP
.ti +4
[WIFISYN\]UVMAP

Compute the dirty image associated to the internal uvxy table. This
command is equivalent to the following sequence: SETUP, UVGRID, FFT WIFI
/DIRECT /XY, WIFI2VISI, FFT VISI /INVERSE, COMPLEX VISI TO REAL.

1 WIFI2VISI
.ti +4
[WIFISYN\]WIFI2VISI

Shift-and-average the wide-field hypercube to get a ``standard'' visibility
UV plane, which can then be FFTed to get the dirty image.

[WIFISYN\]WRITE Buffer File [/PLANE First Last]
 
Write the specified output File from the specified internal buffer (UV,
