ObsVis
The CIAO 4.0.1 patch contains improvements to the proposal-planning tool ObsVis.
Changes to ObsVis
- 
    Highlights include: - 
        Implementation of new grouping, "grid", which allows the user to create and manipulate rectangular regular grids of fields-of-view (FOVs). Users can resize, move and rotate the grid as well as add, remove, and modify single grid members. 
- 
        Group members can have attributes synchronized so that the changes of one FOV in group are mirrored by other members. 
- 
        Improved checking to prevent members of a synchronized group from occupying the same ds9 frame and members of a compound group from occupying different frames. 
 There are also a number of user interface upgrades, including: - capability chip labels on and off
- a new preference setting for node boundaries colors
- the target point marker size reflects dither pattern size for selected instrument
- name resolution from target name input
