At first i thought this might be a problem from the draglink re installation (since that could affect the za error). but cband hi and sbn did not show the same offset, so this is probably a re installation error. ... On 10sep13 i updated the za constant term ( in the pointing models for sbw, cband) to correct for this error. cband za constant : -86.0 => -78.13 asecs . ...

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. ...

... 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. ...

... This past spring, as Comet Hyakutake decorated our evening skies, I received a telephone call from an upset parent.

They may be bright overall, but all that light is coming from a big area of space. ... OK, you say, I found Comet Hale-Bopp this evening. ... Does the comet have a tail? ...

... These plots show spectra (either count rates or ux) and the background count rates. omgrismplotplot can be used to display a single spectrum or multiple spectra, produced by omgrism. The input FITS les must contain net count rates, background count rates and the associated errors. The spectra must follow a regular binning scheme (i.e. equispaced wavelength bins). omgrismplot allows the user to input the device type (e.g. Xwindow, Postscript, ...) for output. ... 7 Output Files 1. ...

Figure 4a. The defocus in arcseconds of blur on the image plane is shown as a function of time for the night of August 14. Arrows mark the times at which the telescope focus was manually changed. The labels show the magnitude of the changes made. The squares show measurements of the defocus just prior to and after manual focus changes. ... Below I will show clear indications of errors in the secondary motions which are probably contributing significantly to focus errrors in the telescope. ...
