Here is a zip file of the three data sets for problem set 8 .
There are a couple of things that you should note:
These are real-world-size data acquisition files (i.e., many MB), and part of the point of this problem set is to learn how to deal with memory-intensive tasks like this. You may have to hack around a bit: only reading in 1000 points at a time, etc etc. If you have unavoidable trouble because of the size of these data sets and your (computer's) memory, please come see me.
To decompress this archive, just double click it. ('unzip ps8data.zip' will do the same thing on a unix box)
