I am trying to setup the parameters in Image Simulation analysis. However I donnot know what to choose for oversampling that could make sense with my detector setting.
I have the input bitmap image, field of stars, with 583x441 pixels in width and height. I have a detector pixel size of 0.0028mm with 8192x8192 pixels. Increasing the oversampling will generate a better simulated picture indeed. But I donot know what should I select for oversampling of the source bitmap to have a realistic simulated image.
Choosing 16X versus None for oversampling drastically change the PSF and simulated imge of course as below.
Also for the field height, I have defined my fields in incident angles and it is defficult to understand for me what field height I need to choose to cover 441 pixels of the input image.
