... The sband transmitter measures reflected power using directional couplers at: . ... waveguide along rotary floor out to turnstile, horn . ... horn . ... Any water in this piece of waveguide would flow away from the antenna reflected power coupler that is next to the horn . ... We can see a changed in the reflected power as we go from high to low za (if water in the waveguide) using the network analyzer. the null at 25 feet is probably the distance from the turnstile to just beyond the rotary coupler...

... In reality, the measured amplitude is always smaller due to atmospheric turbulence and instrumental degradation, thus the amplitude measured on a science target has to be normalized by the amplitude measured on a calibrator. Calibrators are rarely unresolved, and if bright ones are needed, they tend to be big enough to require good estimates of their angular diameter. ... A catalog of bright calibrator stars for 200-m baseline near-infrared stellar interferometry (Merand et al. ...

home education > sharing the universe . ... Some social researchers who study how people spend their free time classify amateur astronomers and other amateur scientists as members of the " serious leisure " world, meaning their dedication to their favorite science does not constitute a hobby meant to simply pass the time, but is instead an earnest pursuit for knowledge and understanding. ... We also know that many amateur astronomers regularly engage in education and public outreach (EPO) activities. ...

... More on 51 Peg: . The discovery of a Jupiter--mass planet in orbit around the solar--type star 51Peg has been reported by Michel Mayor and Didier Queloz (Geneva Observatory) on October 6th at the 9th Cambridge workshop on "cool stars, stellar systems, and the sun" held at Florence (Italy). ... Recall that the measurements of radial velocity only yield v sin i which in turn gives us M sin i. For most values of i, sin i will be greater than 0.5 and this gives a mass estimate of 0.5 Jupiter masses. ...
