What should I learn to make astrophysical measurements from open data?
Suppose I want to measure the rotation speed of galaxies to generate galactic rotation curves like these: https://en.wikipedia.org/wiki/Galaxy_rotation_curve
What should I do and what should I learn?
I think I should get some data from a radio telescope, measure the distance to the galaxy and compare the emission frequencies of the left and right sides. Anything else?
How is everything done in a scientifically correct way?
I have chosen "I" as the level of the question, but any answer of any level is welcome, even "B" and "A"
Thank you
