Stripes in images come from 2 sources - one is some remaining bad data
or a less than perfect calibration. The other could be from poor imaging
parameters. The CELLSIZE you should use depends on your UV data
while the IMSIZE depends on how big an area you need to image. Feeding your
UV data set to SETFC with adverbs CELLSIZE and IMSIZE initially 0.0 will
provide you with advice on this subject. You might even need multiple facets
- stripes can also come from a source well out in the beam imaged incorrectly
due to not taking the need for facets into account.
The only things to tell SETFC is the name of the data set and the size of the
field you wish to image.
