move to DM transform
caseyjlaw opened this issue · comments
Currently, rtpipe uses a brute force dedispersion algorithm. We should move to a tree-like algorithm that actually transforms from (f,t) to (dm,t) space.
This will be tricky, since gridding and dedispersion are coupled due to the delay beam effect.
This will probably never happen. Focusing on GPU implementation of fast dedis+grid+fft.
