imagerpositiontest.set_imaging_options - Function



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();
