Next: DWELL Up: Details of SCHED Parameters Previous: DOVEX Contents . The topic of controlling scan timing is discussed in detail in the Scan Times section . ... DWELL is a very similar parameter except that, with DURation , the scan starts GAP seconds (perhaps adjusted by the old parameter PRESCAN after the previous stop time while with DWELL , the scan will start at least GAP seconds after the previous stop time, but, if necessary, will wait longer to allow all antennas to reach the source. ...

SAOtng supports display of photon event data contained in raw files, similar to its support for FITS Binary Table extensions (e.g., X-ray event lists). ... Because event files do not usually contain enough information to generate an image, we have adopted some conventions for specifying how to interpret the data in these files and for how to bin rows of events into images. To image an event file, it is first of all necessary to define the structure of the events in the event file. ...

L-Narrow Cal Values . On 18 December, 2000, the L-Narrow cals were re-measured, with the results shown below. Prior to 18 December, '00, the L-narrow Cal values were assumed to be 1.85 1.91 for A B polarizations, respectively, at all frequencies. This means that gain curves obtained before 18 Dec '00 assume old cal values, and curves determined after 18 Dec '00 assume new cal values. ... lbn cal values measured 18dec00 . ... calval polA [K] . calval polB [K] . ... 1.81 . ...

Allows you to specify a drift scan: motion at a constant velocity along a great circle. ... The path starts at the new object position (though the telescope actually intersects the path later, see Subtleties ). ... Note that the units are always /sec for both axes. ... The velocity along the path is 0.01 /sec. ... The path is assumed to start when you hit the Slew button (more precisely, when the TCC parses the command). However, it takes the telescope awhile to slew to meet the specified path. ...

... The measurements themselves should be stored in a column with the label SIGNAL. ... Programs will expect that SIGNAL represents the integration of the photon flux for the exposure time given in the EXPTIME column (see section ). ... In that case, the column label should be RAWMAG; see Table . Programs will expect RAWMAG to be the usual negative logarithms of intensities; that is, RAWMAG values only use EXPTIME in determining weights. ...

... Let us assume to begin with that there is no source at a given location, only background. Let us calculate the probability that the observed counts at that location are due solely to background. ... The routines described in the present section are designed to take as arguments the probability cutoff (actually a cutoff in likelihood is used) and the background, or expectation value for the counts, and use them to calculate the minimum value of source counts which is detectable at those levels. ...

... The initial descriptions of the FITS format provided a simplified method for describing the physical coordinate values of the image pixels, but deliberately did not specify any of the detailed conventions required to convey the complexities of actual image projections. ... They were CRPIX n for the reference pixel location on pixel axis n , CRVAL n for the coordinate value at that pixel, CDELT n for the increment at that pixel in the coordinate value, and CTYPE n for the type of coordinate. ...
