deepCoadd objects belong to catalogs identified by (patch, tract, filter), while forced_src objects belong to catalogs identified by (visit, ccd, filter, tract). If I understand well, objects which are common to deepCoadd and forced_src catalogs share the same “id” (in fact “objectId” in forced_src and “id” in deepCoadd).
The question is how can we identify the forced_src catalog that contains a given object which is present in a deepCoadd catalog ?
If this association is not possible at the object level, is there a function which returns the list of forced_src dataId matching a given (patch, tract, filter) ?
