Parameter Explanations

imagename

''

Name of the input image

pbimage

[ ]

Name of the primary beam image which must exist or array of values for the pb response. Default “”

outfile

''

Output image name. If empty, no image is written. Default “”

overwrite

False

Overwrite the output if it exists? Default False

box

''

Rectangular region to select in direction plane. Default is to use the entire direction plane.

region

''

Region selection. Default is to use the full image.

chans

''

Channels to use. Default is to use all channels.

stokes

''

Stokes planes to use. Default is to use all Stokes planes.

mask

''

Mask to use. Default is none.

mode

'divide'

Divide or multiply the image by the primary beam image. Minimal match supported. Default “divide”

cutoff

float(-1.0)

PB cutoff. If mode is “d”, all values less than this will be masked. If “m”, all values greater will be masked. Less than 0, no cutoff. Default no cutoff

stretch

False

Stretch the mask if necessary and possible?
