STAR Geometry in simulation & reconstruction

STAR First Cut and Production Geometries

Follow the link below to find the list of geometries implemented for a given year / RHIC run.  In general, the most recent version of the geometry (highest letter) should be used for simulations.   The availability of the geomtries in a given library (geometry.so or xgeometry.so) is indicated in the table.  NOTE:  xgeometry.so is preferred for all production geometries since 2006.  We do not support geometries after 2011 in the old geometry.so library.

The geometry naming scheme is as follows:

Geometry tags take the form Y<year><revision> or Y<year>_<configuration><revision> where <year> is  the 4-digit year, <revision> is a single letter denoting a  different approximation of the detector in a given year, and <configuration> denotes a distinct reconfiguration of the detector.  e.g. HFT installed or out.

  • First cut geometry tags (e.g. y2010, y2011, etc... ) are the first approximation to the STAR detector, suitable for online production.  Minor changes which should not affect tracking may occur during the run.
  • Production geometry tags (e.g. y2010a, y2010b, ... y2013_1a, y2013_2a, etc...) are denoted by a trailing letter appended to the first cut tag.  Once established, these geometries will be frozen in the DEV library, forming a reference for the production which used them.  In general, the latest geometry tag will be the best approximation of the STAR detector.
  • Asymptotic geometry tags (e.g. y2004y,  y2010x, y2013_1x, y2013_2x, etc...) are tags with a trailing "X" or "Y" in their name.  These are TEST geometries, whose definition in DEV may change without notice, and should not be used in data production, simulation, embedding or offline analysis.

  • Simulation data timeline is proposed to begin @ 20111210. Values for the initialiation of the Year 11 timeline (simulation values) are expected to appear in the time range [20111210,20101215[
  • Real data timeline is proposed to start from 20111220. Initialization values for the RealData timeline are expected to appear at a date > 20111220.

NOTE: From y2012 on, FTPC, PHMD, and SCON (aka SVT support cone) are removed.

defined in SL14a.

These are the reference geometries
for production P14ia [*].
