-------------------------------------------------------------------------------
UV Table creation package 				A. Dutrey 20-jun-1997 
-------------------------------------------------------------------------------
Window interface to create a UV Table from calibrated CLIC data.
The calibration parameters are in agreement with the standard calibration 
performed by @pr:x_calib (by R.Lucas) i.e. RF, Amplitude and phase 
calibrations are antenna based. Phase calibration is ``internal'' for Rec.1, 
``external'' for Rec.2.

To create the table, the options are the following:
Continuum data: table 'name' 
Line  Data: TABLE 'NAME' or (using ``Options for LINE'' ) 
	    TABLE 'NAME'/FREQ FREQ_NAME FREQ_VALUE/RESAMPLE .... VELOCITY

Active Buttons:
---------------
UPDATE  To update the table parameters.

GO	To create the Table after setting the parameters.

CREATE_THE_TABLE  same than GO.

Inputs:
-------
2 TFILE 
	Name of the calibrated file. The extension, .ipb or a .hpb, needs 
	to be mentioned. 

2 TNAME
	Name of the UV table. No extension please.

2 TSTATUS 
	A logical to say if you want to create a new table (YES) or if
        you want to add visibilities to an existing table (NO).

2 TSOURCE
	The name of the source. You need to give it in capital letters.

2 TOFFSETS 
	Value of the offsets in '', the defaults are 0'' and 0''. 

2 TSCANS
	The scan range used to create the UV Table. Set FIRST = 0 and 
	LAST = 10000 for all scans (the default).

2 TQUAL
	Minimum data quality required for data selection. From 1(excellent) 
	to 8(very bad). The default is 4(average). See Button CHOICE. 
	
2 TREC
	Select the receiver 1 or 2. See button CHOICE. 

2 TMODE
	Select the mode of the UV table: LINE or CONTINUUM. See button CHOICE. 

2 TBAND
	Select the receiver bands used to create the table. These are LSB
	USB or DSB. See button CHOICE.

2 TDOSUB1
	Select the subband L01 of the cross-correlator. 

2 TDOSUB2
	Select the subband L02 of the cross-correlator. 

2 TDOSUB3
	Select the subband L03 of the cross-correlator. 

2 TDOSUB4
	Select the subband L04 of the cross-correlator. 

2 TDOSUB5
	Select the subband L05 of the cross-correlator. 

2 TDOSUB6
	Select the subband L06 of the cross-correlator. 

2 TDOPHASE
"Use Atmospheric Phase Correction ?"
	To create the table with (YES) or without (NO) the atmospheric phase 
	correction mode. The default is NO.  
	Must be set to the same value as used for the calibration.

2 TDOANT
"Antenna-based Calibration ?"
	To create the table with (YES) antenna-based calibration or with
        (NO) baseline-based calibration. This logical must be set to YES 
        except in some exceptional cases.

2 TLINENN
"Change Line Parameters ?"
	To create the LINE table without any spectral resample or change in 
	frequency name or value (NO) or to change these parameters (YES).
	If you select YES then you have to change the parameters in the 
        option `` Line parameters ''

2 TRESAMP
"Resample Spectral Data"
	To resample your line table (YES). It uses the option /RESAMPLE of
        the CLIC\command. If you select YES then you have to change the 
        parameters in the option `` Resampling parameters ''
