LUCIFER User Manual 7.3.2 Issue 1.3 47 The Telescope Control GUI This GUI uses a direct service connection to the Telescope Control Server (TCS) interface. An error when starting the Telescope Service might be caused by a non running interface on the TCS side. Please inform the LBTO instrument scientist for support. The GUI (Fig. 21) follows the same philosophy as the Instrument Control GUI, the Commit button sends the new setup to the telescope service. Figure 21: The LUCIFER Telescope Control GUI provides all features to set up the telescope. Pointing On the left side of the GUI the current position of the telescope is shown, including the rotator, position and parallactic angle. It is updated regularly so the user is able to follow the telescope motion. Note: When these text fields are empty, it indicates that a connection to the TCS is not working properly or a subsystem is not running on the TCS side. This can be checked by the Telescope Operator. Offset Telescope This panel is necessary for the acquisition process. The user can choose a position angle (PA) offset and telescope position offsets. There are three pull down menues available: • CoordSys Lets the user choose the valid coordinate system. 1. RADEC Offsets are interpreted as sky coordinate offsets. 2. DETXY Offsets are interpreted as detector coordinate offsets. This option is useful for the acquisition procedures.
