19 // Geometry class for EMCAL : singleton
20 // EMCAL consists of layers of scintillator and lead
21 // with scintillator fiber arranged as "shish-kebab" skewers
22 // Places the the Barrel Geometry of The EMCAL at Midrapidity
23 // between 80 and 180(or 190) degrees of Phi and
26 // EMCAL geometry tree:
27 // EMCAL -> superModule -> module -> tower(cell)
29 // absId -> nSupMod -> nModule -> (nIphi,nIeta)
32 // EMCAL_PDC06 (geometry used for PDC06 simulations, kept for backward compatibility)
33 // = equivalent to SHISH_77_TRD1_2X2_FINAL_110DEG in old notation
34 // EMCAL_COMPLETE (geometry for expected complete detector)
35 // = equivalent to SHISH_77_TRD1_2X2_FINAL_110DEG scTh=0.176 pbTh=0.144
37 // EMCAL_FIRSTYEARV1 - geometry for December 2009 to December 2010 run period;
38 // fixed bug for positions of modules inside SM
39 // (first module has tilt 0.75 degree);
40 // the sizes updated with last information from production
41 // drawing (end of October 2010).
43 // EMCAL_COMPLETEV1: Same fixes as FIRSTYEAR and 10 SM instead of 10 + 2 one_third SM, for 2011 runs
45 // EMCAL_COMPLETE12SMV1: contains 12 SM for runs from year 2012 and on
47 // EMCAL_WSUC (Wayne State test stand)
48 // = no definite equivalent in old notation, was only used by
49 // Aleksei, but kept for testing purposes
55 // You can create the AliEMCALGeometry object independently from anything.
56 // You have to use just the correct name of geometry. If name is empty string the
57 // default name of geometry will be used.
