------------------------------ Structure of data for RockstarExtended (hlist) files-----------------------------

The data is stored as HDF5 format. The file name is set according to the below rule. 
<Name of catalog>_<redshift>_hlist_<data_id>.h5

data_id: [1-11]
Properties are divided into eleven categories. Each file contains one category. The details are given below.
