simulator.setconfig - Function

2.6.1 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.

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,
