... 88, Jan. 1983, p. 1-15. l. A survey of extragalactic radio sources made using driven declination scans is reported covering an area of about 0.07 sr to a limiting flux density of 35 mJy. The fast-scan survey was carried out at a galactic latitude greater than 17 deg with the NRAO 91-m telescope operating at 4.755 GHz, and the 480 sources detected were reobserved at 1.4 GHz with the National Astronomy and Ionosphere Center 305-m telescope at Arecibo. ...

... Archives . ... Statistically speaking, ?false sources? are generally in the domain of Type II Type I errors, defined by the probability of detecting a signal where there is none. ... More than 2.3% of the sources are flagged as spurious. ... Type II error is claiming no signal when there is signal (failing to reject the null hypothesis when the alternative is true). Type I error is rejecting the null hypothesis when the null is true, i.e. detecting signal under no signal. ... Chandra Blog . ...
