What is Editing ?

``Editing'' is identifying and removing the bad data from the data set. CLIC offers several ways to do that: scan selection, tagging data with a quality indicator, selective flags associated to the individual components of the array (antenna pointing, phase lock, correlator, etc...).

Whatever tool the astronomer uses, keeping a history of the calibration and editing steps is important. We emphasize the need to maintain a history procedure detailing all the scan selections and flagging events, with enough comments to understand the reasons for these events. A good complement to this procedure is a listing of all the observations where the same events are detailed in comments inserted at the appropriate place.
