LBT Q Eng/SW Review DIMM – Differential Image Motion Monitor

2 JKraus 21-Jul-2008LBT Q Eng/SW Review Highlights Johannes Schmidt, Max-Planck Institute for Astronomy, Physics thesis DIMM system designed, built, tested and installed Hardware: Robotic telescope mount for tracking Hartmann Mask Celestron 14” telescope and focuser CCD Camera Rack mount computer Software: CentOS GNU C++ Integration TCS GUI Prototype

3 JKraus 21-Jul-2008 LBT Q Eng/SW Review Progress Hardware DIMM hardware is mounted on the telescope, upper right, inside System Integration Fiber connection from DIMM to control server in lower treehouse DIMM server controls the hardware and communicates to a client running in Ptolemy Client communicates to TCS and reads data from the Data Dictionary TCS Data Dictionary Items defined and implemented Message string, Seeing number, Status, Time Operation Pointing of the mount A catalog of stars created for LBT for every sidereal hour Finds a star and tracks based on a mathematical model Calculates a “seeing” number Control remotely from control room

4 JKraus 21-Jul-2008LBT Q Eng/SW Review Open Issues Technical Writing data to TCS (Data Dictionary) Tracking Automatic operation Client side on Ptolemy may not be permanent home Data to Environmental GUI Bisque proprietary software Resource Only Johannes has experience running the software System needs more rigorous testing Need to define a path for maintenance and upgrades of hardware and software Documentation Code Completion Technical Reference Manual User Manual

5 JKraus 21-Jul-2008LBT Q Eng/SW Review Planning (Q3/2008) Writing data to Data Dictionary GUI Implementation for Observers Automation needs to be defined and tasked. Operators need experience using the DIMM Review Documentation
