<description>If the change in the mask size in a particular channel is less than minpercentchange, stop masking that channel in subsequent cycles. This check is only applied when noise based threshold is used and when the previous clean major cycle had a cyclethreshold value equal to the clean threshold. Values equal to -1.0 (or any value less than 0.0) will turn off this check (the default). Automask will still stop masking if the current channel mask is an empty mask and the noise threshold was used to determine the mask.

<description>Input single dish PSF image.
This single dish PSF cube must contain the effective SD beam in the center of the image,
for each frequency channel, normalized to peak 1. The coordinate system should ideally
be the same as the SD image cube and contain per-plane restoringbeams that represent the
effect SD beam per frequency.
If the sdpsf is set to a blank string (sdpsf="") an approximate PSF cube will be automatically
calculated internally by using per-plane restoring-beam information from the regridded sdimage
to evaluate 2D Gaussians.
In the future, we will provide an option to auto-generate Airy disk beams derived from
the specified dish diameter.
