I decided my life could not possibly go on until I knew what "elvisgogo" does, so I downloaded the tarball and poked around. it's a pretty ordinary numpy + pandas + matplotlib project that makes graphs from csv. one line jumped out at me: str_0 = ['refractive_index','Na','Mg','Al','Si','K','Ca','Ba','Fe','Type'] the university of st. andrews has a laser named "elvis" that goes on a remote controlled submarine: https://www.st-andrews.ac.uk/~bds2/elvislaser.htm I was hoping it'd be about go-go dancing to elvis music, but physics experiments on light in seawater is pretty cool too.
