Package | synthesis | |
Module | qimager | |
Tool | qimager |
Set various cycle control parameters for
multi-field and wide-field imageing.
Synopsis
setmfcontrol(cyclefactor, cyclespeedup, stoplargenegatives, stoppointmode)
Description
Control parameters for mosaicing or wide-field imaging which are not required in
single field deconvolution are set here to streamline the user interface.
As multifield and widefield imaging is accomplished by deconvolution in cycles,
many of these parameters control how the deconvolution cycles are ended.
Arguments
cyclefactor
Cycle threshold = this * max sidelobe * max resid
Allowed:
Float
Default:
1.5
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:
Int
Default:
2
stoppointmode
Stop multiscale altogether if the smallest scale recieves this many consecutive components
Allowed:
Int
Default:
-1
Returns
Bool
Example
imgr.setmfcontrol(cyclefactor=2.0, cyclespeedup=niter/10,
stoplargenegatives=T, stoppointmode=10);
