. This diagram illustrates how a background image may be repeated within the content and padding areas of a box. In this example, a background image is first centered within a box (established by the BODY element of the example). The box contains paragraphs of text, shown in gray to make them discrete. The image, a blue wavy line on a pale yellow background, is then repeated vertically, to the top and bottom of the BODY box. The effect is to create a wavy band down the center of the page. Return to image.

The VLTI Calibrator Selector Tool is a tool intended to assist in the selection of suitable interferometric calibrators for VLTI observations with MIDI and AMBER. It uses a model of the VLTI and its instruments to assess the fringe visibility, given the observed bandpass, the geometry, spectrum, and coordinates of the target and the time at which the observations are to be made. ... The tool offers an HTML/Java based interface and consists of two pages. ... The quality flag depends on LDD_chi2. ...
