In November 2017 the FACT Collaboration decided to make a first step into the direction of Open Data and release a sample of 17.7 hours of Crab Nebula observations measured in November 2013 available to the general public, along with simulations needed to perform analysis of this data sample.
We encourage to use this data for training, education and outreach for FACT and gamma-ray astronomy in general.
Both FACT Data Analysis chains start from this data format.
To analyse the data, telescope metadata is needed.
This data is provided as one standard fits file per service for each night here.
Especially important for the analysis are the
YYYYMMDD_DRIVE_CONTROL_TRACKING_POSITION.fits files, containing the pointing direction of the telescope measured every two seconds and the
YYYYMMDD_DRIVE_CONTROL_SOURCE_POSITION.fits containing information about the currently observed source. These two files are needed for the FACT-Tools standard analysis.
