Observations are added to the proposal as one or more sessions. A session consists of a target list, a total Integration Time and, optionally, scheduling and conditions constraints.
To add sessions to your proposal, click on the 'New Session' button.To add targets to a session, click on the 'Targets' button for that session. All Sessions must have an estimated Integration Time appropriate to observe all the targets in the target list.
To over-ride the default scheduling constraints for a session, click on the Session icon on the left hand panel, and then select 'over-ride default constraints' on the right hand panel.
Within each session, the same or a different target can be chosen from the target list (e.g. select the Targets container in an observation) or a totally new target may be defined. Similarly, the target details (coordinates etc) may be altered (select the name of the target in the left-hand panel).
Sessions may be cut, copied and pasted using the usual buttons.
