The SVDecon module can operate in several implicit modes, depending on how many star samples - if any - are provided;
The latter mode of operation is usually the preferred and recommended way of using the module, and takes full advantage of the module's unique spatially variant PSF modelling and correction capabilities.
The module automatically grays out parameters that are not being used, and may also change (zero-out or disable) some parameters in line with the different modes as they are accessed.
When the subject is lunar or planetary in nature, no star samples are typically available. The "Planetary/Lunar" preset button configures the module for optimal use in these situations.
Finally, details of the mode being used, are reflected in the message below the image window.
The Bin module puts you in control over the trade-off between resolution, resolved detail and noise.
And all this is just what Tracking does for the deconvolution module.
All light in your image is spread according to a Point Spread Function (PSF), not just the stars.
Understanding these important points will make clear why some of the various parameters exist in this module, and what is being achieved by the module.
The SVDecon module requires a mask that marks the boundaries of stellar profiles.
You can convert everything you see to a format you find convenient. Give it a try!
