Radio Interferometry Principles . Radio Interferometry Signal Processing . ... A radio interferometer consists of a pair of directional antennas that are tuned to receive radio emissions from a source in a desired RF band. ... The antennas are pointed at the radio source of interest and are set up to receive the signal and process it into a form suitable for transmission to the correlator. ... In connected element interferometry, the digital signal goes directly to the correlator. ...

... The results are used in quasireal time by the observing process, but also as input by hardware quality control, by the dynamical scheduler, and by the Science Pipeline. Among processing operations are the calibration of the atmospheric absorption, of phase radiometric correction, of pointing scans, of phase and amplitude reference measurements, .. ... Using the last few measurements, we will determine a provisional amplitude calibration curve (to be also used by the Quick Look pipeline). ...

... A three-cell test section roughly representative of the primary mirror was provided for this test by the Steward Mirror Lab. ... Additionally, the tests are intended to determine relative airflow vs. pressure drop characteristics for each of the air flow patterns so the results can be evaluated both as a function of flow rate and of pressure drop along the flow path. ... The bottom (top as installed) was cut out so it could close the chamber for heating and be removed for the cooling tests. ...

... We can investigate projection of this distribution onto the celestial sphere in two ways: in terms of lines of constant SN frequencies per one square degree for all galaxies from the sample (Figure 36 ), and in terms of constant GW amplitudes at a given SN frequency per square degree (Figure 44 ). ... Figure 45: The sky distribution of the total supernova frequency from nearby galaxies in terms of lines of equal frequencies per square degree. ...

Next: Introduction . ... We present the results of spectrophotometry of two Blue Compact Galaxies (BCG) known from earlier studies as very metal-poor objects. ... UM 382, according to our data, is significantly more metal-rich: its 12+log(O/H) = 7.76 0.07 in comparison to the cited earlier value 7.45. ... Thus the latter two galaxies should NOT be considered as extremely metal-poor BCGs. galaxies: abundances - galaxies: photometry - galaxies: individual (UM 133, UM 283, UM 382) . Introduction . ...

It could be that SETI signals have arrived at the Earth, but are lower then the noise level, and our receivers cannot detect them. ... Fig. ... It follows that two zones form around the star with civilization X: "Zone Yes", where its SETI signal can be detected, and "Zone No", where its signals are hidden by noise (Fig. ... In practice, it is more efficient to use a time factor, since the problem of SETI contact does not limit the duration of the signal element and semantic text. ...
