The GPS and GPS Common-view are the methods used to refer measurements made using the Parkes observatory clock ("UTC(PKS)") to Universal Coordinated Time (UTC). ... Transfer from UTC(AUS) to UTC is possible via the offsets reported in Circular T. These methods of the clock corrections commenced on the MDJ 50844. ... Currently used scheme is fully integrated into tempo2 , where fairly regularly sampled values of the offset between pairs of clocks are recorded in ASCII text files, one pair per file. ...

The preliminary version of documentation of the format for the interchange of calibrated optical/IR data being developed by Tom Pauls of NRL and John Young of COAST was presented and a number of issues discussed. The proposed format is in the general form of a relational database with different components stored in FITS binary tables. ... Should there be a single data table type that includes all data types, or multiple table types, one per data type? What data types are needed? ...

... DFS projects To-do lists rules and recommendations . Each DFS project has to manage action items, i.e. create and update his own To-Do list. These lists are all accessible from the specific DFS Department Home Pages (select one project). ... Each To-Do list has to be described via 2 files: . ... The 2 To-Do list files must be regularly updated by each DFS project manager, in order to be reviewed during every corresponding DFS bi-monthly project meeting held with the DFS Department Head . ...
