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

data_id: [1-3]
Stored in "SFR" directories. Originated from UniverseMachine SFR output. 
The data is divided into three categories (filename data1-data3):
data1: Basic
data2: Position
data3: Additional properties

data_id: [4-12]
stored in "SFH" directories. Originated from UniverseMachine SFH output. 

For more detail, please see the "Description of galaxy properties" section below.
In that section, N is the number snapshots before the current snapshot (e.g., N=50 at z=0 for the Uchuu-UM).

Mvir (Msun/h, float32)
virial mass (Bryan & Norman 1998) of the dark matter halo

sm (Msun, float32)
true stellar mass of the galaxy

icl (Msun, float32)
true intracluster stellar mass inside the dark matter halo

sfr (Msun/yr, float32)
