In recent times the POS task has been largely superseded by the use of the tdfeng engineering interface see Figure 1 11 Under normal operation the main purpose of the POS task is was to provide a mimic display of the 2dF positioner It also includes the ability to control most of the positioner functions In normal operation however the positioner should be controlled through the control task s positioner control window whenever possible rather than through the POS task 1 4 The Control Task The main window of the control task is shown in Figure 1 2 This window contains status displays for the five subsystems managed by the control task Telescope ADC CCDs Positioner and the AAOmega spectrograph Any of these sections can be removed from the display by clicking the button in the top right hand corner It can be restored to the display using the Display menu Y 2dF Control Task 5 x Eile Commands Display Windows Options Help me Control Task Status OBSERVING UT Time 24 Oct 06 16 20 17 Telescope Time 25 Oct 06 02 20 17 Telescope Hal ADC 3 AAOmega 27 Status Tracking Parallatic 1376 Obs Slit Mean RA 02 11 58 74 ADCRA 02 12 22 2dF P1 Mean DEC 00 38 52 ABC HEC 00 41 07 m S21 BUA S HA 02 16 Angle A 1971 l OPEN ZD 4541 AngdeB 781 l gt S Air Mass 1 42 Pos Error 9 Full Status more more more CDs 4 Positioner 5 Observing
