simulator.setconfig - Function

2.4.1 Set the antenna configuration
Description

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

allowed:

stringArray

Default:

ALT-AZ []

antname

Vector of names of all antennas

allowed:

stringArray

Default:

ALT-AZ []

coordsystem

Coordinate system of antenna positions [x,y,z], possibilities are ’global’, ’local’ , ’longlat’

string

Default:

global ’global’

referencelocation

Reference location [required for local coords] Position Measure of Coordinates of array location. E.g me.position(’ITRF’, ’30.5deg’, -20.2deg’, 6000km’) or me.observatory(’ALMA’)

allowed:

any

Default:

variant ALMA position measure

Returns
bool

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’);  
 sm.setconfig(telescopename=’VLA’, x=xx, y=yy, z=zz, dishdiameter=diam,  
                mount=’alt-az’, antname=’VLA’,  
                coordsystem=’local’, referencelocation=posvla);
