The computed band passes. ... The interim correlator input is filtered by 8 analog filters (50 Mhz wide at the 260 Mhz IF... one for each sub correlator). ... For bandwidths of 25 Mhz and below the real data stream is digitally down converted to complex samples I, Q streams. ... The Top figure is the halfband filter bandpass computed from the filter coefficients. ... The computed filter has aliased power, extra IQ filtering, and two applications of the filter on the resulting real bandpass. ...

... Different statistical tests are used to compute the probability of a given hypotheses being correct. ... For single quantities, a confidence interval is estimated for the desired significance level. ... When the underlying distribution is normal, the ``Student's'' t and the distributions are used to estimate the confidence intervals for the mean and standard deviation, respectively. ... For this purpose the test variable . ... Special tables give the confidence interval for this test variable. ...

We have reanalyzed the Large Magellanic Cloud's (LMC) ultraviolet (UV) extinction using data from the IUE final archive. Our new analysis takes advantage of the improved signal-to-noise ratio of the IUE NEWSIPS reduction, the exclusion of stars with very low reddening, the careful selection of well-matched comparison stars, and an analysis of the effects of Galactic foreground dust. ...

. You can use the diff command to compare the contents of two directories: diff directory1 directory2 . The information given by the command tells you what to do to make the directories match. If there is no difference between the directories you are returned to the shell prompt . diff reports if a file or directory is only to be found in directory1 or directory2 . It also reports any line by line differences for files that are common to each directory. Example .

Next: CONCLUSION Up: CHIRPLET TRANSFORM SUBSPACES Previous: Nondilational Chirplet Transform . Suppose we choose a windowed sinusoidal FM signal for our mother chirplet. Such a signal has a frequency that periodically rises and falls (much like the vibrato of musical instruments or the wail of a police siren). ... Figure 14 . ... Using the warbling mother chirplet, we also computed the ``dilation-dilation'' ( ) plane of the chirplet transform (Fig. 16 ) for the pendulum data. ...

Figure 5: The location of CPDтИТ20 1123 on the log g T eff diagram, compared with normal sdB stars (Edelmann et al. 2003), helium-rich sdB stars (Ahmad Jeffery 2003; Naslim et al. 2010), helium-rich sdO stars (Stroeer et al. ... We present a fine analysis of the bright intermediate helium sdB star CPDтИТ20 1123 (Albus 1) which shows it to be cool, for a hot subdwarf, with T eff 23 000 K and with a surface helium abundance 17 per cent by number. ...
