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 of long-term monitoring of Gigahertz-Peaked Spectrum sources were found the statistically significant differences (0.05 significance level) in the high-frequency spectral index distribution between subgroups of galaxies and quasars. ... This can mean that the electron energy distribution for GPS galaxies is steeper than for GPS quasars. ... The first area corresponds to GPS-quasars that have statistically larger value of redfhift, second area corresponds to GPS-galaxies. ...

... S71-43052 (August 1971) --- A close-up view of a container full of green-colored lunar soil in the Non-Sterile Nitrogen Processing Line (NNPL) in the Lunar Receiving Laboratory (LRL) at the Manned Spacecraft Center (MSC). This sample, broken down into six separate samples after this photo was made, was made up of comprehensive fines from near Spur Crater on the Apennine Front. Astronauts David R. Scott and James B. Irwin took the sample during their second extravehicular activity. ...

DIGITAL WDC EXCHANGE FORMAT . FOR OBSERVATORY 1.0 MINUTE VALUES 1. ... DATA-1 .. DATA-60 are 1-minute values of the given element for that hour. ... Typically, digital 1-minute values received by WDCs from organizations operating automatic magnetic observatory instruments are averages of more frequendy sampled values, e.g. 10-second point samples. ... If the method used to obtain 1-minute average values is important to a user, the WDC will assist in determining the exact procedure applied. ...

... Optical constants: . crystalline silicate . ... Deternimation of the optical constants was made as follows: (i) reflectance of the polished samples was measured in the range 1 - 500 micron and the refractive index in the infrared region was estimated by mean of Kramers-Kronig analysis; (ii) in the region 0.25 - 0.9 micron the real part of the refractive index was obtained from spectroscopic ellipsometry; (iii) transmittance of a self-supporting splat was measured in the range 0.4 - 8 micron. ...
