I chose to focus on spectral classifications B, A, and F. I made this decision because B spectral type stars are too hot to have substantial convective envelopes, while F classification stars have well developed convective envelopes that can cause magnetic braking, and A-type stars provide an intermediate comparison between these two cases. I chose not to focus on O type stars due to the lack of absorption lines in the range of Rice University's spectrograph. Stars later than F-type were also excluded because their rotational velocities tend to be below our spectrograph's resolution limit of around 20 km/s, making it difficult to get accurate measurements on rotational broadening.
These are the steps I took in performing my data reduction using my data collected from Rice University's Lhires III Shelyak Spectrograph on a 23 micron setting:
