The eROSITA pre-processing and NRTA software

Presenter: Ingo Kreykenbohm

We present an overview of the eROSITA pre-processing (preproc) and Near Real Time Analysis (NRTA) software. As a first step, the preproc pipeline will decode the binary telemetry files and write the event and housekeeping (HK) information to separate FITS files. In a second step, the resulting event files are then merged and chronologically sorted. Finally one event file is created for every eroDay and stored in the archive. Health checks (like badpixel detection, see poster by C. Grossberger) are then performed to identify possible problems of the instrument as early as possible and to ensure the scientific quality of the data. The resulting detector and HK graphs are displayed for visual inspection using a web interface. The third step is to run the eROSITA standard pipeline to obtain sky images, source catalogs, and spectra.
