Dataset of simulated trajectories for the standard X10-Y13 optics of VAMOS++ large acceptance spectrometer operated at GANIL. The trajectories were simulated using the standard magnetic ray-tracing code zgoubi [F. Méot, The ray-tracing code ZGOUBI, Nucl. Inst. and Method. A 427, 353 (1999) doi:10.1016/S0168-9002(98)01508-3] The description of the coordinates used can be found in [A. Lemasson and M. Rejmund, Fast trajectory reconstruction techniques for the large acceptance magnetic spectrometer VAMOS++, Nucl. Instr. and Methods A, 1054, 168407 (2023)] The X10-Y13 optics is the reference operation optics for the VAMOS++ spectrometer, where focalisation of reference trajectories with reference relative magnetic rigidity (Delta=1) is focalised at distance from reference target position (0,0,0) of 10 meters in X coordinates and 13 meters in Y coordinates.

Rejmund and A. Lemasson, to be submitted) for the reaction point (XT,YT,ZT), angles (Theta, Phi) and relative magnetic rigidity (Delta) along with calculated path length (Path in cm) and focal plane coodinates (Xf in mm, Tf in mrad ,Yf in mm,Pf in mrad) at 760 cm from reference target point (XT=0mm,YT=0mm,ZT=0mm) Total number of trajectories : 201439908 Exemple of file content and format from SBatch1.root : *******************************************************************************Tree :Zgoubi_Data: Zgoubi Data Tree **Entries : 16787344 : Total = 738807635 bytes File Size = 521233213 ** : : Tree compression factor = 1.42 ********************************************************************************Br 0 :Theta : Theta/F **Entries : 16787344 : Total Size= 67164630 bytes File Size = 54902081 **Baskets : 151 : Basket Size= 3200512 bytes Compression= 1.22 **............................................................................**Br 1 :Phi : Phi/F **Entries : 16787344 : Total Size= 67164320 bytes File Size = 56471544 **Baskets : 151 : Basket Size= 3200512 bytes Compression= 1.19 **............................................................................**Br 2 :YT : YT/F **Entries : 16787344 : Total Size= 67164165 bytes File Size = 36543919 **Baskets : 151 : Basket Size= 3200000 bytes Compression= 1.84 **............................................................................**Br 3 :XT : XT/F **Entries : 16787344 : Total Size= 67164165 bytes File Size = 40217461 **Baskets : 151 : Basket Size= 3200000 bytes Compression= 1.67 **............................................................................**Br 4 :ZT : ZT/F **Entries : 16787344 : Total Size= 67164165 bytes File Size = 28130958 **Baskets : 151 : Basket Size= 3200000 bytes Compression= 2.39 **............................................................................**Br 5 :Delta : Delta/F **Entries : 16787344 : Total Size= 67164630 bytes File Size = 51296387 **Baskets : 151 : Basket Size= 3200512 bytes Compression= 1.31 **............................................................................**Br 6 :Xf : Xf/F **Entries : 16787344 : Total Size= 67164165 bytes File Size = 53593982 **Baskets : 151 : Basket Size= 3200000 bytes Compression= 1.25 **............................................................................**Br 7 :Tf : Tf/F **Entries : 16787344 : Total Size= 67164165 bytes File Size = 56694022 **Baskets : 151 : Basket Size= 3200000 bytes Compression= 1.18 **............................................................................**Br 8 :Yf : Yf/F **Entries : 16787344 : Total Size= 67164165 bytes File Size = 44962368 **Baskets : 151 : Basket Size= 3200000 bytes Compression= 1.49 **............................................................................**Br 9 :Pf : Pf/F **Entries : 16787344 : Total Size= 67164165 bytes File Size = 48240655 **Baskets : 151 : Basket Size= 3200000 bytes Compression= 1.39 **............................................................................**Br 10 :Path : Path/F **Entries : 16787344 : Total Size= 67164475 bytes File Size = 50166521 **Baskets : 151 : Basket Size= 3200512 bytes Compression= 1.34 **............................................................................*
