The First G-APD Cherenkov Telescope is the first Imaging Atmospheric Cherenkov Telescope using Geiger-mode avalanche photodiods as photo sensors.
FACT persues two main goals, on the on hand it serves as technology demonstrator for the SiPM technology in gamma-ray astronomy, on the other hand, it continuously monitors the brightest extra-galactic sources of TeV gamma rays.
From the start on, FACT has made the analysis results of the on-site Quick-Look-Analysis available to the public.
Since November 2017, FACT has gone one step further and has released a datasample of 17.7 hours of high quality Crab Nebula observations along with extensive simulations to the public.
This datasample is available from the telescope raw data upwards on our Open Data Page.
