.. list-table:: **itall**
   :header-rows: 0

   * - Value
     - Explanation
   * -  | (D=0)
     -  | Options for tally output after every batch.
   * -  | =-1
     -  | No output.
   * -  | =0
     -  | Output only numerical data files.
   * -  | =1
     -  | Output both numerical data and image (\*.eps) files [#]_ .
   * -  | =2
     -  | Output to different files. (file name = specified file name + batch number))
   * -  | =3
     -  | Output transition of tally results and these statistical errors as a  function of the history number (or batch number).  These values are output into a file \'\*\_StD\' where \'\*\'  indicates the file name specified in the tally section.  This function is available only for [t-track] and [t-point].
   * -  | =4
     -  | Output to different files by independently summarizing each batch  results (file name = specified file name  :math:`+`  batch number).  This option cannot be selected in the batch variance mode  (istdev=1). This function is available only for [t-track] and  [t-deposit].

.. list-table:: **IMeVperN**
   :header-rows: 0

   * - Value
     - Explanation
   * -  | (D=1)
     -  | Option for the energy unit in tally outputs for nuclei (ions). Previously, this parameter was named **iMeVperU** with a default value of 0 (MeV). From Version 3.36, the name has been changed and the default value has been switched to 1 (MeV/n) to ensure consistency with the unit settings in the [Source] section (which primarily uses MeV/n). Please note that with this change, the default unit for ion tally results will switch from MeV to MeV/n. Note that the name **iMeVperU** can still be used, but not recommended.
   * -  | =0
     -  | Output in total kinetic energy (MeV).
   * -  | =1
     -  | Output in kinetic energy per nucleon (MeV/n).

   * - Value
     - Explanation
   * -  | (D=1)
     -  | Options for the tallying timing when the tracking particle is  in a field, which constantly changes the particle's momentum, such as a  magnetic, electromagnetic, or gravity field.
   * -  | =0
     -  | Tally at reaction or surface cross (normal).
   * -  | =1
     -  | Tally at each step of the transport.

When IMeVperN=1, the unit of nucleus energy is changed from [MeV]  to [MeV/n] in outputs of [t-track], [t-cross], [t-point], [t-product], [t-time], [t-interact].  For example, in the case of [t-track] with unit = 2,  quantities in units of [1/cm :math:`^2` /MeV/source] are converted to those in  [1/cm :math:`^2` /(MeV/n)/source]. 

[t-track] uses deltm as the step length to describe  particle trajectories in fields that continuouly change particles' momenta,  such as a magnetic field.  To describe the trajectory curve more smoothly, adjust the setting of deltm.

.. [#]  From Ver. 2.86, the dmax of each nucleus is also output.
