The vopt parameter is computed from the optical measurements in the compilation of redshifts by rejecting outliers and measurements marked for their bad quality and computing a weighted average of the remaining measurements. ... The optical measurements are first selected and converted to a uniform system as: vop = cz + zeropoint(iref) , where cz is the compiled value and zeropoint(iref) a zero-point correction for the reference iref . ... Finally, the individual corrected measurements are combined. ...

... Binary orbits in the acceleration/period plane . Circular Orbits . ... We first present the equations for the period and acceleration of a pulsar in an eccentric binary system as a function of its position in the orbit. ... In Freire, Kramer & Lyne (2001) (from where most of this text and following equations are taken), we describe in more detail how circular binary orbits can be determined from the observed periods and accelerations of the pulsar. ... where is the orbital period of the binary. ...

... The binary nature was remarked by Deutsch, approximate orbital elements were at first derived in Potsdam. Recently, 53 Cam was directly resolved by speckle-interferometric measurements of McAlister et al. and Balega. Combining with the spectroscopic elements the determination of the absolute values of the system parameters should be possible. In the present paper a revision of the spectroscopic orbital elements and a comparison of spectroscopic and speckle data have been carried out. ...

Next: Other parameters of the Up: The Model Previous: Initial binary parameters . As we only deal with initially massive binary systems (their primary's mass is higher than 10 ), which are capable of evolving off the main sequence during less than years, the compact stars left behind stellar evolution are (in the case of the most massive stars) NSs and BHs. ... For a NS belonging to a binary, the evolution complicates as the secondary star evolves: for example, (recycling), etc. ...

... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...

Target Acquisition Reference Information . There are limits to the brightest and bluest stars that can be acquired with mirrors N1 and N2 because of the very high fluxes of these objects. Figure 7.3 on page 91 shows the limits for these two mirrors as set in the Constraints and Restrictions Document (CARD). ... Once you have predicted an acquisition count rate, you then determine the integration time per dwell point during the target acquisition: STEP-TIME. ... STEP-TIME Constraints . ...

The determination of the detector parameters is based on sets of images of a spatially uniform-illumination scene (flatfield frames) and without any illumination (dark frames), putting a plug in place of the filter, taken at a series of exposure times. ... We interleave before and after each exposure time in the series of flatfield frames a set of reference images at an exposure time of 1 sec to determine the possible temporal variation of the illumination level. ...
