Tutorial 1.2

[martinberoiz]

Tutorial 1.2 has the phrase "This doesn't look correct at all!" and "This looks a little more like what we expect for the amplitude spectral density of a gravitational-wave detector."

I think that without further explanation, it's not obvious to a person that sees the graph for the first time what is "not correct at all" or why after windowing, the data looks better. I think we should add what specific parts of the graph don't look correct and why, and what should we expect and why. Otherwise let's remove those?

I'd be happy to rephrase but tbh I don't know why the graph doesn't look good. 🤷‍♂️
