We will specify an output name of `BiCEP_converted.csv`. This gets dumped in the folder with the datafiles. For your convenience, we have included a set of MagIC formatted data to convert to the BiCEP format. This may take a few minutes"

This site is a lava flow erupted in Hawaii in 1935 and originally analyzed by Cromwell et al (2015). Because this eruption occurred in the age of instrumentation, we know that the original field this lava flow was erupted in was approximately 36.4 μT.\n"
