// placed inside another hexagonal cell made of Cu (ECCU) with larger
// radius, compared to ECAR. The difference in radius gives the dimension
// of half width of each cell wall.
// These cells are placed in a rectangular strip which are of 2 types
// EST1 and EST2.
// Two types of honeycomb EHC1 & EHC2 are made using strips EST1 & EST2.
// 4 types of unit modules are made EUM1 & EUM2 for PRESHOWER Plane and
// EUV1 & EUV2 for VETO Plane which contains strips placed repeatedly
//
// These unit moules are then placed inside EPM1, EPM2, EPM3 and EPM4 along
// with lead convertor ELDA & ELDB and Iron Supports EFE1, EFE2, EFE3 and EFE4
// They have 6 unit moudles inside them in each plane. Therefore, total of 48
// unit modules in both the planes (PRESHOWER Plane & VETO Plane). The numbering
// of unit modules is from 0 to 47.
//
// Steel channels (ECHA & ECHB) are also placed which are used to place the unit modules
//
// In order to account for the extra material around and on the detector, Girders (EGDR),
// girder's Carriage (EXGD), eight Aluminium boxes (ESV1,2,3,4 & EVV1,2,3,4) along with
// LVDBs (ELVD), cables (ECB1,2,3,4), and ELMBs (ELMB) are being placed in approximations.
//
// Four FR4 sheets (ECC1,2,3,4) are placed parallel to the PMD on both sides, which perform
// as cooling encloser
