Main camera display

The main camera display displays either the full image or part of it. If only a part of the image is displayed, the display has a red border (Figs. 6 and 7). During exposures a status bar pops up in the upper left part of the display. The CCD cooling temperature is displayed in the upper right corner of the display.

The color bar subwindow at the bottom of the main camera display can be used to set the cuts of the image display or to show information about the pixel currently located below the mouse pointer.

To change the cuts move the mouse into the color bar subwindow and click on the left mouse button. The current cuts are displayed and they are changed by moving the mouse holding the left mouse button pressed. Dependent on the position of the mouse in the color bar subwindow the lower or the upper limit is modified.

If the mouse pointer is within the display the x,y-position (in pixel) and the intensity level under the mouse position is given. Values in parentheses give the x,y-position in arcsec relative to the center of the image.

Several operations are possible using the mouse within the display (Fig. 13).
