invert's interpolation kernel?
Posted: Fri Nov 13, 2015 8:22 pm
Hi, does anyone know if there is documentation describing invert's uv gridding process? In particular, describing the choice of gridding interpolation kernel? Also, is the interpolation kernel different from CASA's?
I have looked in the manual, as well as papers describing MIRIAD, and had a quick look in the source code, but nothing states the details of the process. I know that "Interferometry and synthesis in radio astronomy, A. R. Thompson James M Moran; George W Swenson" suggests that prolate spheroidal wavefunctions are the common choice, but even then, does not suggest how many nearest neighbours are used for interpolation.
Thanks,
Luke
