simulator.setfield - Function

2.4.1 Set one or more observed fields

Description

Set one or more observed fields, including name and coordinates. Can be invoked multiple times for a complex observation. Must be invoked at least once before sm.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:	’OBJ’
distance	Distance to the object
	allowed:	any
	Default:	variant 0m

Returns
bool

Example

    sm.setconfig(telescopename=telescope, x=x, y=y, z=z,
                 dishdiameter=d.tolist(),
                 mount=[’alt-az’], antname=padnames,
                 coordsystem=’global’, referencelocation=pospbs);

    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.settimes(integrationtime="10s", usehourangle=True,
                referencetime=me.epoch(’TAI’, "2012/01/01/00:00:00"))
    sm.observe(sourcename=’SIMU1’, spwname=’XBAND’,
               starttime=’0s’, stoptime=’3600s’)
