2.3.1.0 imager.make

imager.make - Function

2.3.1 Make an empty (i.e. blank) image
Description

Make an empty image using the current image parameters. Often this is unnecessary, but you will typically need to use this if you wish to deconvolve a set of images. The steps are to make the empty images that you require to be deconvolved, and then pass them into clean as a vector of strings.

Arguments


Inputs
image	name of output image
	allowed:	string
	Default:
async	Run asynchronously in the background
	allowed:	bool
	Default:	false

Returns
bool

Example

im.defineimage(nx=1024,ny=1024, cellx=’30marcsec’,celly=’30marcsec’,
nchan=1, stokes=’IV’, phasecenter=me.direction(’mars’));
im.make(’mars.moving’);
im.defineimage(nx=1024,ny=1024, cellx=’30marcsec’,celly=’30marcsec’,
nchan=1, stokes=’IV’,
phasecenter=me.direction(’J2000’, ’12:23:48.7’, ’-15:56:32.9’)
im.make(’mars.fixed’);
im.clean(algorithm=’mf’, model=[’mars.moving’, ’mars.fixed’],
image=[’mars.moving.restored’, ’mars.fixed.restored’])

This makes two empty images, one moving with mars and one fixed in J2000, and then deconvolves the two jointly using clean. Finally the images are restored.
