wow! so interesting! really tiny jedi astronomers then!

What I don't get is how they managed that degree of temporal resolution of the incoming signal.

they were using bigger binoscopes, Clive.

video imaging and storing the collected spectra wasn't the problem but = according to the abstract - crunching through the numbers was.
that's why they had to focus on really strong impulses for analysis, leaving out everything that was weaker.
which could mean that the Jedi did not only shoot the laser for 1 trillionth of a second but actually longer - in differing strengths within 1 application.
