How should the EMSphInx spherical calibration parameters be set?

Hello everyone, I'm trying to use EMSphInx for spherical calibration, but the results aren't very good. I have some questions about parameter settings.

1. First, regarding the Binning and Binned Pixel Size parameters, if I select 5×5 (128×96) in my test, should my binning be set to 5, and the Binned Pixel Size to 96?

2. For the Scan Width parameter, I tried 88, but the results weren't good. I tried higher parameters (e.g., 158, 172, 203, 221, 263), but the software crashes. Does this require a higher computer configuration?

3. Can EMSphInx calibrate data from a hexagonal grid? If so, how do I set the X step and Y step (I'm using a hexagonal grid with a step size of 0.4 for data acquisition)?
