I am planning to publish a research paper based on my internship and don't know in what order I must include the author names or whom to include in the paper. Professor A was the primary reason for me to join the internship, while Professor B is just my guide who initially didn't approve of me doing the internship but later started to motivate me. Intern C had helped me a lot to complete the project whose help has been crucial to me. All 3 actually told me to publish the paper and Professor B guided me with the websites and reviewing my papers. But Professor A also initially guided me with the paper. How am I to rank these people for the authors in the paper?
Prof A- Initial guidance with some ideas to improve my presentation and strong support without which I wouldn't even have taken up the internship
Prof B- Support only at the later stage to publish paper and reviewed the papers
Intern C-Can't imagine myself to have completed the project (based on which the research paper is constructed) without her.
Thanks in advance!
