Position Editor Toolbar

The Position Editor Toolbar provides quick access to the most commonly used features from the menu bar. The buttons have the following action:

• Open - bring up a file selection dialog to load a previously saved image.
• Back - move backwards in image history list
• Forward - move forward in image history list
• Cut levels - bring up a dialog of showing the distribution of pixel values for the displayed image. The minimum and maximum display levels can be set either with the slider or the Auto Set buttons.

 

• Catalogs - opens the catalog navigator for defining and executing custom guide star and image server queries.  It is also useful for seeing the detailed results.
• Guide Stars - opens the Guide Star Selection dialog (below) for doing quick guide star searches.  The coordinates for the search is the base position of the observation selected in the Program Editor.  Likewise the Instrument is set using the instrument component of the selected observation in the Program Editor.  The Guide Star Type and the Catalog is remembered from the last query.  The combination of the instrument and guide star type determine the minimum and maximum radii and the limiting magnitude for the query.  Custom queries can be constructed using the catalog navigator.

• Images - queries the the default image server using the base coordinates of the observation selected in the Program Editor.  If no default is set then a Image Server dialog (below) queries the user to select a server.  The default can then be changed by selecting a new server from Catalog -> Image Servers in the menu bar (the current default is marked with a black dot) or by selecting an image server with the Catalog Navigator and pressing the Store Settings button (the icon of the default is shaded yellow).
