W-kernel from the imager

[arunkmv]

Is it possible to dump the W convolution kernel when W-projection gridding with the imager as a 3D FITS file? Also some explanation of how the kernels are generated from the input visibilities would also be of great help.

I am facing some problems while using OSKAR 2.7.6, and I hope to ask you for advice. If you check the option in the red box, does it mean that the data we get is intensively corrected for image distortion caused by the increase in the field of view?
What if we want to show obvious non-coplanar baseline effects? In the simulation of the data set using OSKAR 2.7.6, which parameters have an impact on this effect? Thank you very much for your reply.
This is my code:
