== A comparison between eFEDS_Sim3 and eFEDS_Sim4 ==

* eFEDS simulation Version 3
	* eFEDS attitude file according to the launch date of June 12. Typical depth 2.9ks.
        * sixte-2.5.9, simput-2.4.5, with default instrument files.
	* AGN simput: eFEDS_AGN_simput_v3.fits Multiply Flux by 1.7 (a temporary solution to a Simput bug)
	* cluster simput: cwg_clusters/v0.1/efeds_mock.simput
	* galactic background: eFEDS_bkg_simput.fits
* eFEDS simulation Version 4 (EroAgn + EroClusters)
	* eFEDS attitude file according to the launch date of July 13. Typical depth 2.2ks.
        * sixte-2.5.10, simput-2.4.5, with the new PANTER PSF model (tm1_2dpsf_190219v03.fits) and a new vignetting curve (erosita_vignetting_v3.0.fits).
	* AGN simput: eFEDS_AGN_simput_v4.fits, the same as _v3, just cropped for the new field.
	* cluster simput: cwg_clusters/v2/eFEDS_cls_v2_simput.fits
	* galactic background: eFEDS_bkg_v2_simput.fits, the same as last version, just re-made for the new field.


* Attitude file Sim3 (typical depth 2.9ks, 127 deg^2^ ) vs Sim4 (typical depth 2.2ks, 144 deg^2^ )

=== Below compares Sim3,PipelineV7 (left), Sim3,V8 (middle) and Sim4,V9 (right): ===
* Note: Essential parameters were changed between Pipeline V7 and V8 to improve point-source detection efficiency. But they remain the same between V8 and V9.
