deconvolver.clipimage - Function



Package general
Module deconvolver
Tool deconvolver


Zero all pixels where Stokes I is below a threshold


Synopsis
clipimage(image, threshold)


Description
All pixels in the image with Stokes I less than some threshold are set to zero. This is useful prior to self-calibration where one oftens wishes to remove negative pixels from the model. Note that if the image has polarization information, then the polarized part of a pixel is also set to zero if Stokes I is less than the threshold.



Arguments

image   name of image
    Allowed: String
threshold   Threshold
    Allowed: String
    Default: '0Jy'


Returns
Bool


Example
imgr.clipimage(image='clean', threshold='50mJy')
imgr.selfcal(cal='mycal', model='clean');
