Note: If you are experiencing difficulties with the Java applets, please go to http://java.com/en/download/manual.jsp and download the Java virtual maching (VM) for your operating system.
The interactive GOODS field viewer
The interactive GOODS field viewer is a small Java applet providing zooming,
panning and object selection capabilities. The viewer is displayed within the
web browser window and shows the GOODS field, a color map for redshift from
0.1 to 1.5, a panel with menu buttons and information, and at the bottom of
the viewer, the current RA/DEC values to which the mouse is pointing and the
corresponding X/Y position in pixels within the image. The 2095x1318 JPEG image
used in the viewer is a reduced version from the original 8380x5270 FITS file.
Menu Buttons
- Float
Pressing the Float button causes the applet to be displayed in a new window,
which can be resized independently from the browser window. Where the applet
was located, a background image is now shown. A new Dock button replaces
the Float button.
- Dock
The Dock button causes the applet to be re-inserted into the browser window.
After this operation, the Float button replaces the Dock button.
- Redraw
The Redraw button refreshes the image display.
- Reset
The Reset button displays the image in the original position and with no
zoom.
- Zoom out/Zoom in
The Zoom out button decreases the display magnification, while the Zoom in
button increases the display magnification.
Display options
- Background only
In this mode, only the GOODS field image is displayed.
- Obj w/ redshift
In this mode, objects with redshift greater than 0 are marked with a small
circle. The color of the circle changes from blue to red corresponding
to the redshift. Green circles mark objects with ZQ (quality) = -1.
- All objects
In this mode, objects with and without redshift are displayed. Objects with
ZQ=INDEF are considered to have no redshift.
Navigation
- Panning
Pressing and holding the left mouse button while moving the mouse causes
the image to scroll following the movements of the mouse. When a limit
of the image is reached, scrolling will stop.
- Zooming
Pressing and holding the right mouse button while moving the mouse displays
a rubber band that marks the area to which the image will be zoomed in.
- Click on an object
Pointing the mouse to an object causes the Id, RA, DEC, Z and ZQ of that
object to be displayed on the side panel. When the left mouse button is
pressed on the object, then a new browser window will retrieve and display
detailed information about that object, including close-up ACS and DEIMOS
images, as well as the 1d and 2d spectrum.
