main

main is the root directory for the Merged Target List ledgers for the DESI Main Survey. The MTL ledgers record the state of each DESI target as redshift information is acquired. There is a set of ledgers for each of the DESI Main Survey primary programs (dark, bright and backup) as well as for the DESI secondary programs (secondary) and for Targets of Opportunity (ToO).

Subdirectories:

• dark
• bright
• backup
• secondary
