 * Estimate on the performance of the default source detection

Objects Types (planned):

 * AGN
 * Galaxy Cluster
 * Stars
 * Cataclysmic Variables


----

AGN:

 * used the 4 AGN Catalogs by N. Clerc simulations as a "standard" catalog to get sources parameters
 * applied a 5e-15 erg/s flux threshold to the the catalog
 * rescaled the number of sources to match the 4700 skyfields for eROSITA and rolled new positions on a sphere
 * reduced the nbins in the spectra from 1000 to 100 to improve performance of the simulation
 * "remove" galactic NH from input catalog spectra
 * determined NH for each source and applied it to the spectra
 * more than 20.000.000 AGN

----

CV:
 * Catalog of sources (CVS, IPS, POLARS) provided by Axel Schwope
 * applied a flux threshold 1.0e-15 erg/s
 * used unabsorbed flux / model / NH to create spectra useable by SIXTE
 * few 100.000 sources

----

Galaxy Cluster:
 
 * SIMPUT catalog provided by Jeremy Sanders, Sebastian Grandis, John Mohr
 * more than 3.000.000 Galaxy Clusters with images
 * currently up to 1.0e-20 erg/s
 * next simulation will be reduced to match thresholds of other input catalogs

----

Stars:
 * in contact Jan Robrade / Juergen Schmitt - plan to integrate catalog based on parts of the GAIA catalog

Goals:

  • Test of Pipeline (eSASS) environment
  • Test of NRTA environment
  • Test of Data Access Tools (datool)
  • Handling the large amount of data
  • Derive computational requirements
  • Estimate on the performance of the default source detection
