Abstract
Energetic neutral atom (ENA) flux from the NASA TWINS mission (and previously the MENA instrument on the NASA IMAGE mission) is projected along the line of sight to the equatorial plane in GSM coordinates. A Maxwellian fit is used to calculate the ion temperature in each equatorial plane bin, creating 2D maps of ion temperatures. The files are IDL .pro scripts that can be read using a text editor. IDL software is required to run. The primary script is twins_master.pro. The scripts call other scripts that were developed by the TWINS mission team as well as publicly available IDL libraries (eg. Geopack) that are not included here.
