Analysis Software

ELFIN data can be analyzed using the SPEDAS software suite, which stands for "Space Physics Environment Data Analysis Software."

To access ELFIN within SPEDAS, you must download the “Nightly Build” version. Full instructions and links here: SPEDAS Download and Installation. There is also a developer blog and a wiki page with more detailed information on the suite and its use.

SPEDAS is a general-purpose software framework and Graphical User Interface (GUI), which includes code adapted from NASA's CDAweb and can download data from dozens of NASA space missions. It consists of IDL routines which read data in CDF format, as well as other less refined data sets. IDL routines can be used to download, open, analyze, and plot scientific data. For ELFIN, it can download Level 1 (L1) and Level 2 (L2) data quantities and also transform L1 data into L2 data. L1 data is raw, uncalibrated data in CDF format. L2 data is calibrated in physical units. These IDL routines were derived from those used by the THEMIS-ARTEMIS (TDAS), Cluster, Wind, Polar, and FAST missions. In addition to command line invoked IDL routines, the software provides a graphical user interface (GUI) for opening, analyzing, and plotting data. This interface was designed to facilitate use of the most useful IDL routines.
