ToO

The ToO directory hosts a monolithic ledger of Targets of Opportunity. This is used by the DESI fiberassign pipeline to assign special, time-critical, observations.

Note that for the DESI main survey, the Targets of Opportunity ledger that is read by fiberassign is split into two. The ToO.ecsv file hosts Targets of Opportunity assigned on their own special tiles. The ToO-fiber.ecsv file hosts Targets of Opportunity assigned to fibers during the course of normal survey operations.

• ToO-input.ecsv : Minimal information used to derive the Targets of Opportunity ledger
• ToO.ecsv : Targets of Opportunity ledger in a form that can be read by fiberassign (tile overrides)
• ToO-fiber.ecsv : Targets of Opportunity ledger in a form that can be read by fiberassign (fiber overrides)
