# DMU2 validation report (2017-02-02)

- There is no README.
- What is the encoding of the `z_source` column.
- There is no meta information associated.
- Some source have a reliability to -1.  As it's a float column, it's better to
  use NaN.  That was changed.
- I added a `specz_id` column with a position base identifier like we have in
  the specZ table on the VO server.

  mean that there is no redshift.
