# DMU2 validation report (2017-03-14) - There is no readme. - There is no meta information files (the `yml` files). - 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. - The update catalogue is `EGS-specz-v2.1_hedam.csv`.
