imagerpositiontest.set_mfcontrol_parms - Function

	Package	synthesis
	Module	synthesistester
	Tool	imagerpositiontest

Set control parameters for multi-field imaging tests.

Synopsis
set_mfcontrol_parms(cyclefactor, cyclespeedup, stoplargenegatives, stoppointmode, scaletype, minpb, constpb)

Description
Set control parameters for multi-field imaging tests. These parameters are passed to (p)imager.setmfcontrol() by make_image when there is more than one field being imaged.

Arguments

cyclefactor		Cycle threshold = this * max sidelobe * max resid
		Allowed:	Float
		Default:	3.0
cyclespeedup		Cycle threshold doubles in this number of iterations
		Allowed:	Float
		Default:	-1
stoplargenegatives		Stop the multiscale cycle for the first n cycles when a negative comp is found on the largest scale
		Allowed:	Intger
		Default:	2
stoppointmode		Stop multiscale altogether if the smallest scale recieves this many consecutive components
		Allowed:	Integer
		Default:	-1
scaletype		mage plane flux scale type
		Allowed:	String: 'SAULT'|'NONE'
		Default:	"NONE'
minpb		Minimum PB level to use
		Allowed:	Float > 0
		Default:	0.1
constpb		In Sault weighting the flux scale is constant above this PB level
		Allowed:	0 > Float > 1
		Default:	0.4

Returns
T

Example

- include 'imagerpositiontest.g';
- ipt := imagerpositiontest();
# set up a multi field clean test using the Sault flux plane scale
- ipt.set_sim_parms(nfields=4);
- ipt.set_deconvolution_function('clean');
- ipt.set_clean_parms(algorithm='mfclark',niter=2000);
- ipt.set_mfcontrol_parms(cyclefactor=2.5,scaletype='SAULT',constpb=0.2);
T
- ipt.dotests();
