GUMS-10 statistics
GUMS-10 is the 10th version of the Gaia Universe Model Snapshot, a simulation of the expected contents of the Gaia cataloge run at the MareNostrum supercomputer (please notice that any use of these data should acknowledge the use of its resources). The models used and the characteristics of GUMS-10 are described in the following article (accepted for publication):

This page is the complement of Robin (2012), providing the full statistics of GUMS-10 that are the basis of the paper. A first set of more complete statistics can be found in this internal DPAC document:
GAIA-C2-TN-UB-XL-028 Gaia Universe Model Statistics - version 10

(Warning: the interpretation of the statistics for multiple systems can be tricky. Please contact the authors in case of doubt.)
Full statistics can be obtained directly from the simulator Statistical Analysis Module files:
  • Download the java GATDisplayer tool: this tool can be used to open the SAM files and visualize the statistics. Run it with java -jar GATDisplayer.jar and see XL-028, section 2.4 for details.
  • Download a SAM file from this list and open it with GATDisplayer to get the corresponding statistics (refer to XL-028 for a description of the contents of each file). Regional statistics on the same format are available on request (e-mail to xluri[at]am.ub.es)
  • GUMS-10 data has been generated with GOG and GaiaSimu v.10.0.0 using GaiaMdbDm-10.0.0. See the GaiaSimu 10 Universe Model Overview for more technical details on the Gaia Simulator Universe Model.

Support: all our resources are commited to the development of the Gaia simulator for the needs of the Gaia Data Analysis and Processing Consortium (DPAC). Unfortunately we can not provide user support for GUMS-10 or GATDisplayer outside DPAC, but questions can be addressed to xluri[at]am.ub.es and will be answered, if possible, in a best-effort basis.

Disclaimer: GUMS-10 is the result of the ongoing work of Coordination Unit 2 in the framework of the Gaia Data Analysis and Processing Consortium. Its results may be corrected and/or superseded by future versions of the simulator.
