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 model for each receiver differs from the sband narrow model by an offset in azimuth (great circle) and zenith angle .These offsets are computed by tracking the above source (or sources) rise to set and computing the difference in pointing errors between sband narrow and the new receiver. ... The table below has the rms pointing error for each receiver on CTA21 and the rms of the difference in pointing error between the receiver and sband narrow: . receiver . Rms azErr . Rms zaErr . ...

... User Guide ] Task: uvsfit Purpose: Fit point sources to a given vis file. ... You can reduce the data volume by averaging in frequency using the line parameter (apply bandpass first) or selecting a subset of the data. If you want to produce model or residual visibilities at full resolution for all the data, you can run UVSFIT again with all source parameters specified and fixed. ... Key: sspar This gives initial estimates of source spectral parameters. ... 1 The spectral term alpha1 is fixed. ...

... Using a simple 2-D Gaussian Point Spread Function (PSF) on a constant (flat) sky background, I derive a theoretical photometric and astrometric performance model for analytical and digital PSF-fitting stellar photometry. ... The photometric performance is maximized when either the effective background area or the effective-background-level measurement error is minimized. ... An important, but frequently ignored, noise source is the uncertainty of the measurement of the effective background level ( )...

... To be read in conjunction with Chapter 5 of the WFPC2 Instrument -Handbook, Version 4.0. Here we supplement the Instrument Handbook with short discussions of the use of PSF subtraction to maximize image dynamic range and to obtain accurate stellar photometry. We also discuss a source of error in the published values of the HST aperture correction. ... Thus faint objects near bright objects can be difficult to detect and to distinguish from PSF artifacts. ... Last updated: 06/16/98 10:38:00 . ...

The technical memorandum: A Kernel Model for Precision Timekeeping (PostScript) describes an engineering model which implements a precision time-of-day function for a generic operating system. ... The model changes the way the system clock is adjusted in time and frequency, as well as provides mechanisms to discipline its time and frequency to an external precision timing source, such as a pulse-per-second (PPS) signal. ...

Figure 55 shows the ``Green functions'' for the double compact binary merging rate   evolution assuming no collapse anisotropy. ... Another way that diverse peculiarities in the - distribution induced by the sources evolution could arise is connected with a possible non-monotonic character of the star formation rate in galaxies. ... 22 ] Figure  56 shows two-dimensional cuts through the parameter space. ...

ON THE IMPACT OF THE GALACTIC ABERRATION ON VLBI-DERIVED PRECESSION MODEL Z.M. MALKIN Pulkovo Observatory Pulkovskoe Ch. ... Corrections to adopted precession rate are usually computed from the linear trends in long-term time series of celestial pole offset (CPO), which are the differences between the measured and the theoretical coordinates of the celestial pole. ... CONCLUSIONS We have estimated the impact of GA on parameters of precession-nutation model derived from VLBI observations. ...
