	Package	synthesis
	Module	synthesistester
	Tool	imagerpositiontest

Set some general options for subsequent processing.

Synopsis
set_imaging_options(ftpmachine, cache, tile, gridfunction, location, padding)

Description
Set some general options for subsequent processing. These options are passed to (p)imager.setoptions() by make_image().

Arguments

ftpmachine		Fourier transform machine
		Allowed:	'gridft'
		Default:	'gridft'
cache		Size of gridding cache in complex pixels
		Allowed:	Integer >= 0
		Default:	0
tile		Size of a gridding tile in pixels (in 1 dimension)
		Allowed:	Integer > 0
		Default:	16
gridfunction		Gridding function
		Allowed:	String: 'SF'|'BOX'
		Default:	'SF'
location		Location used in phase rotations
		Allowed:	position measure
		Default:	F
padding		Padding factor in image plane
		Allowed:	Float >= 1.0
		Default:	1.0

Returns
T

Example

- include 'imagerpositiontest.g';
- ipt := imagerpositiontest();
# set up a single field mem test, changing the default padding
- ipt.set_deconvolution_function('mem');
- ipt.set_sim_parms(nfields=1);
- ipt.set_mem_parms(algorithm='entropy',niter=25,sigma='0.1Jy');
- ipt.set_imaging_options(padding=1.7);
T
- ipt.dotests();
