Parameter Explanations

imagename

''

Name of the input image

region

''

Region selection. Default is to use the full image.

box

''

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

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.

stretch

False

major

''

Major axis of overriding restoring beam. If specified, must be a valid quantity.

minor

''

Minor axis of overriding restoring beam. If specified, must be a valid quantity

logfile

''

File which to write details. Default is to not write to a file.

overwrite

False

Overwrite exisitng ouput file if it exists?
