Simulations of 10 ksec XMM "blank fields".

We have simulated 10 ksec "blank field" pn+MOS exposures, i.e. devoid of nearby bright sources, using SciSim v3.0.0 with the XMM Current Calibration Files as of Dec 11, 2001.

General image properties

A full description of the simulation setup is provided in astro-ph/0202022.

Extended source input

The simulations have been run with two different sets of extended source input:
  • Set 1: Based on Press-Schechter prescription.

  • Set 2: Based on N-body simulation.

Each downloadable package contains:

  • FITS images pertaining to the EPIC pn, MOS1, and MOS2 instruments, produced in two energy bands.

  • a source field FITS file for visual comparison with the above.

  • exposure maps.

  • a list of source properties, including sky positions and fluxes.

  • a README file describing the data products.

Every image file can be freely downloaded and used for whatever purposes. If using these images as a basis for scientific publications, please include the following reference:

We appreciate comments or suggestions on these simulations - as well as requests for other specific simulations. We are mainly interested in detection of extended sources, but welcome collaboration on other issues as well.
