Data Products & Apps by I4DS
Data and tools generated for our publicly funded research projects are open and accessible for everyone.
Data Center | X-ray telescope STIX
Data and tools related to the operation of the X-ray telescope STIX and the scientific processing of its observations
Python Library | IRISreader
Functionality to read IRIS level 2 data by the IRIS satellite and to process it for big data applications. IRISreader works best with a Jupyter notebook.
