Or straight from the browser: Code then Download ZIP.

Installation & Usage

There is no installation, this is portable.

$ cd solar_rotation
$ ./sunspot_analysis.py -h

There is no documentation. Run ./sunspot_analysis.py -h for descriptions of what to do. The data needs to be structured in a specific hierarchy and also specifically named. The file ./rotational_rate_analysis.py contains the calculations to obtain rotational periods.

Shell scripts provided can automate certain file operations, and can be run as

$ ./script.sh arg1 arg2 arg3 …

Check source code for details on what they do and the arguments required.
