Main parameters selection for the WIPE method        K. Bouyoucef 29-March-1998
-------------------------------------------------------------------------------

Initialisation panel for the main parameters of the WIPE image reconstruction 
method. 
Advanced parameters of the method can be accessed through the "advanced 
parameters" button. Most of the time, the defaults will be ok.




Active Buttons:
---------------

GO               Validates the settings of the current panel. Then, read the uv
                 data contained in the file specified in the WIPE_NAME variable.

ABORT            To leave this panel.

HELP             The button you have just pressed.

WIPE_INFO        To display header information related to the file specified
                 the WIPE_NAME variable. Will provide in particular information
                 on the number of channels and visibilities, central frequency...

WIPE_APER        Starts the wipe_aper tool for the design of the aperture to be
                 synthesized in the WIPE image reconstruction method.

WIPE_BEAM        Starts the WIPE_BEAM command that computes the experimental beam
                 and the WIPE Neat Beam resulting from the choice of the aperture
                 be synthesized. Both will be used in WIPE reconstruction method.

WIPE_SOLVE       Starts the WIPE_SOLVE command, the heart of the WIPE image
                 reconstruction method.

WIPE_ERROR       Starts the WIPE_ERROR command for the study of the error
                 propagation in the WIPE reconstruction method.

Don't Push       Useless button.

View Parameters  To invoke the advanced parameters setting panel.

Help             Help related to the advanced parameters of the method.


Inputs:
-------

2 WIPE_NAME
"uv file to process"
        Name of the file that contains the uv data to process.

2 MAP_SIZE
"Number of pixels of the mapped image" 
        Number of pixels in each direction (array of two integers).
        Usually, it is the same value since most of the time we deal with
        square images. 

2 MAP_CELL
"Size of map cell in arcsec"
        Resolution of pixel in each direction expressed in arcsec units.
        vector of two real values.

2 WIPE_PROC
"Channel number to process in uv file"
        Channel number that we want to process in the uv file. If 0 is selected
        it will automatically set the default to 1.
        This is the sic variable one wants to change to process interactively
        several data channels.

2 WCOL
"Channel to use for weighting"   
        The channel to extract weight information from.

2 WEIGHT_MODE
"Weighting mode"
        Two weighting modes are available. The 'UN' or uniform weight mode
        attributes the same contribution to each weight. Whereas the 'NA' 
        or natural mode takes into account the local density of visibilities.
        
2 APERTURE
"parameters of axis of aperture to be synthesized"
        Multiplicative factors to apply on major and minor axis of the default
        ellipse characterizing the aperture to be synthesized in the uv plane.
