override

The override directory hosts ledgers used to override MTL information for secondary targets in the DESI dark-time program. Each entry is copied over the entry for the corresponding TARGETID in the standard ledgers, each time the MTL code is run. Targets are stored in ledgers that are split by HEALPixel (in the NESTED scheme) at a resolution of nside=32.

The filename for each ledger resembles mtl-override-dark-hp-HPX.ecsv, where HPX is the healpixel number.
