Solar and VLBI projects are special as a sensitivity cannot be entered i.e. the user must enter a time estimation. This is similar to overriding the OT's time estimate as the entered time should include calibration and overheads. For VLBI, the time will be for a single 12-m configuration. For solar observing, the time will also be that of a single 12-m configuration, but the OT will also include time for the TP Array.
