Set the antenna configuration

Synopsis
setconfig(telescopename, x, y, z, dishdiameter, mount, antname, coordsystem, referencelocation)

Description
Set the positions of the antennas. Note that the name of the telescope will control which voltage pattern is applied to the data.

Arguments

telescopename		Name of the telescope we are simulating (determines VP)
		Allowed:	String
		Default:	'VLA'
x		Vector of x values of all antennas [currently m]
		Allowed:	Vector
		Default:	[]
y		Vector of y values of all antennas [currently m]
		Allowed:	Vector
		Default:	[]
z		Vector of z values of all antennas [currently m]
		Allowed:	Vector
		Default:	[]
dishdiameter		Vector of diameters of all antennas [currently m]
		Allowed:	Vector
		Default:	[]
mount		Vector of mount types of all antennas (recognized mounts are 'ALT-AZ', 'EQUATORIAL', 'X-Y', 'ORBITING', 'BIZARRE'
		Allowed:	Vector of strings
		Default:	[]
antname		Vector of names of all antennas
		Allowed:	Vector of strings
		Default:	[]
coordsystem		Coordinate system of antenna positions [x,y,z]
		Allowed:	String: 'global' | 'local' | 'longlat'
		Default:	'global'
referencelocation		Reference location [required for local coords]
		Allowed:	MPosition

Example

 diam := [25, 25, 25, 25, 25]
 xx := [50, 100, 150, 200, 250]
 yy := [2, -5, -20, -50, -100]
 zz := [-0.5, -1.0, -1.5, -2.0, -2.5]
 posvla := dm.observatory('vla');
 mysim.setconfig(telescopename='VLA', x=xx, y=yy, z=zz, dishdiameter=diam, 
                mount='alt-az', antname='VLA',
                coordsystem='local', referencelocation=posvla);

In this example we configure an array of 5 dishes set at the VLA position. We use the measures tool to give us the location of the vla.
