Commands that query the setup

 

This class of commands includes commands that query the flags (both EOSGX flags and some GEANT flags), query the setup of the program, and the geometrical setup of the detectors.

  1. FXYZ or /EOS_GEANT/EVENT/FXYZ XP YP ZP


    tabular577

    Find field components at a given point in MARS (MAster Reference System, i.e., CAVE coordinates).

  2. INFO or /EOS_GEANT/EVENT/INFO CH_INFO [ VNAM1 VNAM2 ]


    tabular580

    This command outputs information about many aspects of EOSGX.

    Currently available options are CUTS, DISPLAY, EOSG, FIELD, MEDIA, ONE, TRACKING, TRANS, TREE, Volume names, and XTR.

  3. LOCATE or EOS_GEANT/VOLUME/LOCATE VRF1 VPT(1) VPT(2) VPT(3)
    VRF2 KNUMBV


    tabular584

    This command locates a point known in a particular reference system VRF1 in another system VRF2. As an example, if VRF1 = MARS or CAVE the point is taken to already be in the MAster Reference System (named CAVE in EOSGX). Its new coordinates in the daughter reference system (DRS) of volume VRF2 are then calculated. An optional vector of copy numbers may also be given in order to uniquely identify a volume, in the case of multiple copies of that volume name existing in the geometrical tree. Therefore, the command

    VOLUME/LOCATE PADS 0.0 0.0 0.0 HTPC 1 1
    requests the coordinates of the center (0,0,0) of the first pad in the first pad row in reference system HTPC. The name PADS is not unique, so the vector (1,1) specifies the requested pad. Note that the command
    VOLUME/LOCATE PADS 0.0 0.0 0.0 HTPC
    requests the coordinates of the centers of ALL of the 15360 pads!

    Note also that the GEANT numbering of detector elements is not necessarily equivalent in all cases to the numbering conventions used by the particular detector represented.

  4. STATUS or /EOS_GEANT/EVENT/STATUS

    This command gives the status of flags (e.g., the HIT_JITTER flag) used for diagnostics and control.
