. This diagram illustrates how the definition of a pixel depends on the users distance from the viewing surface (paper or screen). The image depicts the user looking at two planes, one 28 inches (71 cm) from the user, the second 140 inches (3.5 m) from the user. An expanding cone is projected from the user's eye onto each plane. Where the cone strikes the first plane, the projected pixel is .28 mm high. Where the cone strikes the second plane, the projected pixel is 1.4mm high. 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. ...

... It turns out one possibility is a form of matter/energy invented by Einstein in the 1920s to make sure his equations of General Relativity did not predict the Expansion of the Universe. Although Einstein was willing to predict several things with his equations of General Relativity, he obviously thought an expanding Universe was too much, and so he invented the Cosmological Constant, which repels itself, and was meant to balance the force of gravity, and make the Universe static. ...

It seems that every time I try to correct for a pointing error, I have to figure out the sign of the pointing error as reported by the various routines. The pointing error is computed using the heiles calibration scans and by using the turret scans. ... The center of the pattern is the "computed" position of the source using the ra,dec transformation to az,za and any current pointing model. ... X0, Y0 are reported as the error. ... So for turret scans, Add the az,za error to the pointing model. ...
