Compton Spectrometer and Imager Data

Data Directory: <https://spdf.gsfc.nasa.gov/pub/data/cosi/00readme.txt> 

The Compton Spectrometer and Imager, COSI, is a Compton telescope operating in the 0.2-5 MeV energy range and capable of imaging, spectroscopy and polarimetry of astrophysical sources. Such capabilities are made possible by COSI's twelve germanium cross-strip detectors, which provide for high efficiency, high resolution spectroscopy, and precise 3D positioning of photon interactions. This directory gathers the heliophysics data observed during the COSI balloon flights.

The Compton Spectrometer and Imager (COSI) is a balloon-borne, 
soft-gamma ray imager, spectrometer, and polarimeter with sensitivity 
from 0.2 to 5 MeV. Utilizing a compact Compton telescope design with 
twelve cross-strip, high-purity germanium detectors, COSI has three main 
science goals: study the 511 keV positron annihilation line from the 
Galactic plane, image diffuse emission from stellar nuclear lines, and 
perform polarization studies of gamma-ray bursts and other extreme 
astrophysical environments.
