Three-component modelling of C-rich AGB-star winds V. – dataset

The provided data include all parameter files, binary output files, and log
files that are the basis for the publication in MNRAS.

The file 'file_listing.txt' contains a complete list of files and
directories in all gzipped tar files. Each individual gzipped tar file is
formatted as follows:

 Mm.m_Ll.ll_Ttttt_CtOc.cc.tar.gz

where
 m.m  :: the assumed mass of the model, in solar masses
 l.ll :: The assumed luminosity, in log10(solar luminosities)
 tttt :: The effective temperature of the star, in Kelvin.
 c.cc :: The carbon-to-oxygen excess, in log10(n_C/n_H-n_O/n_H)+12

The contents vary according to the model, but here is the general directory
structure:

 nodr/  :: non-drift / PC models
 drift/ :: drift models

 nodr/init
 drift/init :: Initial model files created using John Connor.

File suffixes are the following:

 .par :: Plain-text parameter file that contains all parameters that are
         different from the respective default value in the model.
     Consequently, to see all used parameters it is necessary to look in
     the log file (see below).

 .bin :: Binary file that contains converged models. Each model is stored in
         two versions, first the previous time step and then the current time
     step (both are needed to restart model calculations at that time
     step).

         The initial model file only contains one model; where the previous
     time step data are the same as the current time step data.

         The format of this file is explained below.

         Note! These files can get pretty large and are therefore only
       available for a smaller number of the models here. Please ask the
       corresponding author for the missing files should the need appear.

 .log :: Plain-text log file that shows the used model parameters and a number
         of key properties for each converged model. The encoding of this file
     is UTF-8.

 .inf :: Plain-text secondary log file that contains the header of the
         [primary] log file as well as timing information.

 .tpb :: Secondary binary file that contains a number of properties specified
         at the outer boundary, typically for each consecutive time step.

 .lis :: Plain-text file with the iteration history. Available for some files.

 .liv :: Plain-text file with values specified for a number of properties at
         each gridpoint. Available for a smaller number of files.

 .inp :: Plain-text file that is used to launch a model; some are still there.

 .eps :: Encapsulated PostScript files created by John Connor when calculating
         the initial model.

Model evolution structure - file endings before the suffix:

 _rlx :: Files related to relaxing the T-800 calculations on the initial model
         created by John Connor.

 _exp :: Files related to expanding the initially compact model to using the
         full radial domain.

 _fix :: Files related to the intermediate stage where calculations are changed
         from expansion to outflow.
         
 _out :: Files related to the outflow stage of the calculations; this is what
         you want to look at to see the wind evolution. Results in the paper
     are calculated using these data.

 
 Note! Some outflow stage calculations continue the evolution of the previous
   set of files. The underlying reason for continued calculations is typically
   that the calculated time interval is too short. Such files are typically
   given the extension '_cont.lin_out', '_cont2.lin_out', etc.

Load files:

  Two tools are provided here that can load the binary data files using the
  Interactive Data Language (IDL):

  sc_load_bin (for files with the suffix '.bin'):

    Loads the full content of a T-800 binary file and returns a structure
    with the data.

  sc_load_tpb (for files with the suffix '.tpb'):

    Loads the full content of a T-800 'tpb' binary file and returns a
    structure with the data.

    Note! Due to the way models run on clusters, this file is sometimes
      incomplete; this happens when the model code T-800 is stopped as the
      cluster-specific walltime is reached. If this is the case, it is
      necessary to use the binary file instead, where data are saved
      typically every 20:th time step.

  Alternative tools for use with Python and Julia could be considered for
  writing, but where not yet available when this dataset was made public.
