Re: SETI like tass project

[Doug Welch <welch@physics.mcmaster.ca>]

I fully agree with Dirk's assessment. A time-series analysis
for many hundreds or thousands of points per object to high
frequencies can be quite CPU-consuming. Obviously, the sampling
needs to be appropriate to the task.

Cheers,
Doug
