CALET Image Gallery
The CALorimetric Electron Telescope (CALET) is an
international mission funded by the Japanese Space Agency (JAXA) in
collaboration with the Italian Space Agency (ASI) and NASA. CALET is
mounted on the Exposed Facility section of the Japanese Experiment
Module on the International Space Station (near MAXI). The instruments
record both cosmic rays and terrestrial radiation in low earth orbit

Science

90% confidence upper limit on the GW151226 energy flux between
1–10 GeV in the time window T0 -525 – +211 s. The
thick cyan line shows the center of the field of view of CALET as it moved
in this timeframe, with the plus symbol marking the center of the field of
view at T0. Green contours shown the matching localization
significance map for GW151226 as reported by LIGO.

showing the quadratic sum of systemic and statistical errors.
