Sloan Digital Sky Survey Telescope Technical Note 19970527 Walter Siegmund . ... Pointing Error Budget . ... The interleaved strips and adjacent stripes overlap about 1 arc minute. ... However, a 2-D pointing accuracy of 3 arc seconds RMS leads to acceptibly uniform overlap and minimises the number of cases that require special handling (Table 3). ... A guide fiber bundle diameter of 16.5 arc seconds and a pointing accuracy of 3 arc sec RMS results in 99% initial success in acquiring guide stars. ...

... Although the simulations have been performed for WFPC II and FOS, the results are expected to apply to the FOC and GHRS, respectively. ... The variation of Strehl ratio with focus for eight wavelengths varying from 125 nm to 700 nm for the cameras is plotted in Fig. ... Fig. 4 gives the tolerable focus error for the cameras as a function of wavelength (using the 20%Strehl ratio degradation criterion), and Fig. 5 the tolerable focus error for the spectrographs. ...

... The fitting package in STSDAS (Space Telescope Science Data Analysis System) relies on two basic techniques (one linear and one non-linear) for fitting functions to data. ... Results show that both methods may generate biased coefficients (at the ~few percent level), and over or under-estimate error bars (at the ~10 percent level), in particular from low signal-to-noise data. ... Function coefficient errors are computed directly from the covariance matrix. ... Abscissa is signal-to-noise. ...

The Steady State model of the Universe was proposed in 1948 by Bondi and Gold and by Hoyle. ... At the time the Steady State model was proposed, the Big Bang model was in trouble because the value of the Hubble constant was clearly bigger than the inverse of the age of the Universe. ... Thus the Steady State model has flat spatial sections like the critical density Big Bang model. ... The Steady State model has no adjustable parameters to correct for this error, but the Big Bang does. ...

For a sample of 16 people, the error would be 4/16 = 25%. This a large error since the range of YES vs NO is from 0-100% if 12 people answered yes and 4 people answered no then your result would be: . Percentage yes = 75 +/- 25% . ...
