README.TXT ---------------------- | Files | ---------------------- 10 Raw Text Data Files 1 Word Document 2 Folders containing photos 1 README Text File ---------------------- | Introduction | ---------------------- The flight took place in Australia on April 8, 2017. Multiple recording devices, such as GPS systems and cameras, were mounted onto the balloon in order to record and collect data. The files mentioned above contain that exact raw data that was recorded during the mission. ---------------------------- | Data Files Description | ---------------------------- The 10 raw text files consists of the raw data collected from each subsystem. Each file contains information from each subsystem. The files contain a collection of rows where the first row is used to name the different columns. Each columns is seperated by a comma while a row is seperated by a new line.
