Overview Topics to cover Super- quick review of DD request OpSim runs produced in response to request Highlight differences between runs: # of DDFs, field locaeons Coadded & single- visit depth in DD fields, Eme between obs Overall WFD completeness Process for going forward InteracEon between DD WG / OpSim / Science Council UpdaEng DD white papers & summarizing results from each set of opsim runs (iteraeve process) Timeline 2

So what s next? Process for going forward InteracEon between DD WG / OpSim / Science Council Update DD white papers & summarizing results from each set of opsim runs EvaluaEng DD runs for DD science - DDWG EvaluaEng DD runs for general science - OpSim General report on each iteraeon, recommendaeons & guide for further development SC can provide feedback if necessary Timeline General rule: delay choices as long as possible (first light) Do we need to pick more fields on an earlier Emescale? Review before end of commissioning period 35
