simulator.setfield - Function

2.4.1 Set one or more observed fields
Description

Set one or more observed fields, including name, coordinates, calibration code. Can be invoked multiple times for a complex observation. Must be invoked at least once before observe.

If the distance to the object is set then the phase term includes a curvature for the near-field effect at the center of the image.

Arguments


Inputs
sourcename	Name of source or field (must be specified)
	allowed:	string
	Default:	SOURCE ’unknown’
sourcedirection	Direction Measure of Coordinates of source to be observed. E.g me.direction(’J2000’, ’30.5deg’,’-20.2deg’).
	allowed:	any
	Default:	variant
calcode	Calibration code
	allowed:	string
	Default:	”
distance	Distance to the object
	allowed:	any
	Default:	variant 0m

Returns
bool

Example

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

  sm.setspwindow(spwname=’XBAND’, freq=’8GHz’, deltafreq=’50MHz’,
                   freqresolution=’50MHz’, nchannels=1, stokes=’RR
                   LL’);
  dir0 = me.direction(’B1950’,  ’16h00m0.0’, ’50d0m0.000’)
  sm.setfield(sourcename=’SIMU1’, sourcedirection=dir0);
  sm.observe(’SIMU1’, ’XBAND’, integrationtime=’10s’, usehourangle=T,
                starttime=’0s’, stoptime=’3600s’,
                referencetime=reftime);
