error box

error box

(error circle) The region of uncertainty in the position of a celestial source, defined on a statistical basis. The term is often used in sky surveys of X-ray, gamma-ray, and infrared sources.

Fermi's "error box" measured a few tens of degrees in diameter (the full Moon is only half a degree wide), and NASA's Swift satellite, which sometimes can catch a Fermi event with its more precise X-ray telescope, didn't see any X-ray emission immediately after the GRB.
A mock error box tells the consumer the banner has failed to load because it's too hot, then reminds him/her to stay hydrated.
The error box of the sum (A + B + C) shows that there is no significant difference in the proportion of neutrophils bearing appendages (Figure 2D).
QWHEN I log on to the internet, an error box comes up with Wnad: This program has performed an illegal operation and will shut down.
Gamma rays cannot be focused in the normal sense, but their direction of travel can be triangulated to within a small patch of sky, called an "error box." As soon as the first gamma ray telescopes were placed in orbit they discovered an unusual phenomenon, which became one of the greatest enigmas in astronomy for a long time.
However, such telescopes can only see a small piece of the sky, generally [less than]0.1 [degrees] of arc, and their slew rates are so slow that they may take 10 min or more to begin searching the error box. A target GRB is long gone by then.
It also displays messages in an on-screen error box when it has identified any of more than 70 potential errors and conflicts in the solution process.
Says Henden, "I have access to all the real-time notifications and filter those so that the bursts I post are only the ones with error boxes that would fit on a single CCD frame, or that have had an optical transient already identified." The error box for most GRBs is on the order of 16[degrees] square!
The transmission lines are modeled with three cascaded networks; an intrinsic line segment is embedded between error boxes [R.sub.A] and [R.sub.B] as shown in Fig.
The standard error model for three-sampler analyzers is the 12-parameter error model, shown in Figure 1, while the standard error model for four-sampler analyzers is a cascade of two error boxes with a total of 7 independent parameters.
Other researchers[1-4] usually begin by converting all of the scattering matrices into transmission-matrix form because of the cascade connection between the DUT and the two error boxes. For this special set of experiments, scattering analysis[5] used instead to obtain the following equations for each calibration load (where [x.sub.ij] and [y.sub.ij] are the entries of the 2 x 2 matrices X and Y, respectively): for the through connection T,
