Hi, thanks for reaching out. You can query Mayall z survey catalogs as part of the Legacy Surveys schema. For instance, ls_dr10.tractor is the main LS table in DR10. Our User Manual showcases how to query the databases:

https://datalab.noirlab.edu/docs/manual/UsingAstroDataLab/ClientInterfaces/QueryClient/QueryClient.html#database-queries

and many of our notebooks go into more detail:

Queries would look something like this:

select * from ls_dr10.tractor where mag_z>22.5 limit 100

Let is know if you need more assistance.
