Hi,
You cannot monitor it directly but you can generate a StarMask applying default values of StarMask process over a linear image and fine tune some parameters in order to adjust the result. In general big stars on linear image are not included with default parameters of the process and it can be adjusted increasing the "Scale" value. Higher values of Scale will include larger structures in the generated star mask.
The Structure Growth section on the StarMask tool allow to control the protection of large and small structures in the mask, if you need to extend the area of protection only on the largest stars it has to be increased the "Large-scale" parameter which apply mask protection to larger regions in the image, and at the same time you can control the growth of protection of small stars by decreasing "Compensation" value, or even setting it to cero.
Further processing of the mask can also be done within the StarMask module. If it is needed to increase the protection (higher values in the 0-1 range) you can use "Truncation". Decreasing this value improve protection in the core of the mask structures. Values of 0.5 to 0.3 are enough to have a good protection of stars cores of big stars.
If your image is non linear, also start generating a StarMask applying default values of StarMask process and then fine tune them.
The default "Noise threshold" parameter of the StarMask process generaly generate a mask with a lot of background detected as stars. So the first action will be to adjust this parameter, you have to increase the value in order to prevent the inclusion of noise and fine tune it to adjust the result, checking that the detected stars of the mask are realy stars but not noise.
In general big stars on non linear image are not included with default "Scale" parameters of the process and it has to be adjusted. Higher values of Scale include larger structures in the generated StarMask.
Hope this helps.
Saludos, Alejandro
