... If at any point on such a line we place an ideal compass needle, free to turn in any direction (unlike the usual compass needle, which stays horizontal--such needles exist, see bottom of page) then the needle will always point along the field line (drawing below). ... Because of this attachment, the behavior of electrified gas ("plasma") in space, a gas of free ions and electrons, is dictated by the structure of field lines: Electric currents, for instance, find it easiest to flow along such lines. ...

Next: Spectral Line Processing and Up: Spectral Line Data Reduction Previous: ATCA Spectral Line Correlator . ... The ATCA allows you to observe two frequency setups simultaneously ifsel allows you to load just one of them by setting ifsel=1 or ifsel=2 . ... The RPFITS file does not contain the rest frequency of the spectral line observed, so you need to give this at some stage during data reduction - the earlier the better. The rest frequency can be entered (via restfreq , in GHz) in atlod . ...

Most radio and modem clocks used for a primary (stratum-1) NTP server utilize serial ports operating at speeds of 9600 baud or greater. ... In order to reduce these errors, a set of special line disciplines and stream modules can be configured in the Unix kernel. ... Note that not all Unix kernels support line disciplines and of those that do, not all support System V streams. ... There are two line disciplines and a special streams module included in the distribution. ...

... Many extragalactic objects for which radial velocities are desired display strong emission lines. ... EMSAO, a companion to the cross-correlation task XCSAO (Kurtz et al. 1992), was written to find emission lines automatically, compute redshifts for each identified line, and combine them into a single radial velocity. ... Figure: This EMSAO Summary page shows line centers and fit information for a night sky spectrum. ... To test EMSAO adequately, a lot of emission line spectra were needed. ...

... The spectrum of the Sgr B2 molecular cloud has been surveyed between 215 and 265 GHz towards 3 positions, the dense cores Sgr B2(N)and Sgr B2(M), and the quiescent core Sgr B2(NW). ... The Sgr B2 molecular cloud, located approximately 100 pc from the Galactic Centre and with a mass of , is one of the most extreme cases among star formation sites ( Lis & Goldsmith (1991) ). ... Of the 3 observed positions Sgr B2(N) has the strongest line emission in most molecular species with a few exceptions. ...

The alfa motor controller is inside a huffman box. There a few cables that come out to the motor as well as the ac power line. ... The box was using a corcom 6EF2F power line filter. A preliminary sweep of this filter from 0 to 2 ghz using a synthesize and spectrum analyzer showed that the filter worked well up to about 200 MHz. ... We need to figure a way to improve these filters since many of the devices in the huffman boxes have computers that are running at multiple ghz frequencies. ...
