Samples from Work done with Radio Astronomy Supplies Radio Telescopes
A Direct copy of Work By John Kraus done with the Spectra Cyber Spectrometer
.
Here is CasA recorded with the spectrometer. We see absorption by the dust in spiral arm
between us and CasA. Otherwise we'd just see continuum emission as a fairly
flat line. The frequency of the absorption gives the dust's velocity. We
haven't gotten the hang of doing local standard of rest calculations and
corrections so the frequency is off by about 20 kHz due to Earth's rotation
around the Sun and day/night rotation velocity. But it is good to see that
we can get a graph that closely resembling the one in Kraus at bottom of
page.
