linearmosaic.defineoutputimage - Function

3.1.3 Set the output direction image parameters and name

Description

Define the direction axes output image parameters. The output image will get the same number of spectral and polarization planes as the input images. This function create a fresh new output image. If an image of the same name exist on disk it will be erased. The spectral and polarization part of the image will be identical to the images that are being mosaiced.

The output image will by default be flux correct and the weight image will be ∑ _pA_p²(θ) where the primary beam is A_p(θ)

ny	Total number of spatial pixels in y
	allowed:	int
	Default:	-1
cellx	Cellsize in x (e.g. ’1arcsec’)
	allowed:	any
	Default:	variant 1.0
celly	Cellsize in y (e.g. ’1arcsec’)
	allowed:	any
	Default:	variant
imagecenter	Direction of phase center as a diretion measure
	allowed:	any
	Default:	variant 0
outputimage	output image name
	allowed:	string
	Default:
outputweight	output weight image name
	allowed:	string
	Default:

Returns
bool

Example

lm.defineoutputimage(nx=3000, cellx=’3arcsec’, imagecenter=’19h13m13.469 4d50m09.649’, outputimage=’test.linmos’, outputweight=’test.weightlinmos’)
