image.beamforconvolvedsize - Function

1.1.1 Determine the size of the beam necessary to convolve with the given source to reach the given convolved (source+beam) size


Description

Determine the size of the beam necessary to convolve with the given source to reach the given convolved (source+beam) size. Because the problem is completely specified by the input parameters, no image needs to be attached to the associated tool; eg ia.open() need not be called prior to calling this method.

Arguments





Inputs

source

Three quantities that define the deconvolved source major axis, minor axis and position angle

allowed:

any

Default:

variant

convolved

Three quantities that define the convolved source (source+beam) major axis, minor axis and position angle. Do not specify if beam is specified.

allowed:

any

Default:

variant

Returns
record

Example

 
 
# get the beam necessary to convolve the specified source with to achieve the target convolved source size (source convolved with beam).  
beam = ia.beamforconvolvedsize(source=["1arcsec", "1arcsec", "0deg"], convolved="3arcsec", "2arcsec", "45deg"])
