TUI supports the following offsets: . Object Arc offset by a given amount on the sky (i.e. along the arc of a great circle). ... Arc offsets are useful for moving a different portion of your object or a different nearby object onto the boresight . ... Object Arc XY this is identical to an Object offset except that it has been rotated to align along the instrument x-y axes. ... This is just like the Calibration XY offset, except that it is typically cleared when you slew to a new object. ...

... Most objects in the Dal Model have a name, and an owner (usually referred to as the parent). ... The colon character is used to separate the names of datasets, blocks and columns, but the % character is used before an attribute name. e.g. "set:tab:col%att" is the fully qualified name of the column-attribute with name "att", whose parent column has name "col", whose parent table has name "tab", whose parent dataset has name "set". ...
