I'm interested in a dataset used in a scientific article, but I am not able to find this dataset on the Internet, I guess it is because the dataset was provided by NSTAR (an energy company) that no longer exists (it has merged with Eversource).
I have thought of requesting it to the corresponding author of the article, but I have never sent anything to a MIT visitant professor (female, just for the record) and I have never called a teacher of mine by its title. I think that there is not such a strict culture in Spain of calling everyone by its title. Can anyone help me in writing the letter? Will it bother her if I send such request? How should I start? What should I say about myself? How should I end the letter?
