imager.smooth - Function

2.3.1 Calculate an image smoothed with a Gaussian beam


Description

The model images are convolved with the specified Gaussian beam. By default (normalize=T), the beam volume is normalized to unity so that the smoothing is flux preserving. The smoothing used in restoration is not normalized.

Arguments





Inputs

model

Name of input model

allowed:

stringArray

Default:

image

Name of output smoothed images

allowed:

stringArray

Default:

usefit

Use the fitted value (rather than that specified

allowed:

bool

Default:

true

bmaj

Major axis of beam

allowed:

any

Default:

variant 5.arcsec

bmin

Minor axis of beam

allowed:

any

Default:

variant 5.arcsec

bpa

Position angle of beam

allowed:

any

Default:

variant 0deg

normalize

Normalize volume of psf to unity

allowed:

bool

Default:

true

async

Run asynchronously in the background

allowed:

bool

Default:

false

Returns
bool

Example

 
 
- im.smooth(model=’3C273XC1.clean’, image=’3C273XC1.clean.restored’,  
bmaj=’2.0arcsec’, bmin=’2.0arcsec’)
