STIX data center is a virtual server hosted at FHNW.

1 STIX Data Center tasks

Its tasks include

  • Process STIX raw data & produce high level data products
  • Monitor Data quality and instrument health status
  • Provide data products and data browsing tools for the Solar Physics Community
  • Support STIX operations
  • Data archiving

2 STIX data center architecture

The data flow at STIX data center is shown in the picture below:

Data processing SW mainly written in python. NoSQL DB (MongoDB) used to stored telemetry packets, file metadata and configurations

3 Key Algorithms

3.1 Offline flare location solution

3.2 Flare identification

Quick-look light curves in the energy range from 4 - 10 keV are used for flare identification. 4-sec time bins are first rebinned to 1-min time bins in order to smooth light curves.

Then the smoothed light curves are used to search for peaks. A flare is considered being detected if a peak satisfies several conditions as follows:

  • The peak counts is above 2 sigma of the background.
