1. The AstroStat Slog Blog Archive Spurious Sources
... 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 . ...

2. How to extract MOS spectra of a point-like source and associated matrices
... This thread contains a step-by-step recipe to extract MOS spectra of a point-like source observed in Imaging mode and to create associated response matrices, starting from a calibrated, concatenated event list (either produced with emproc or available as PPS product; here it has the assumed file name MOS.fits ). ... The users should note that the SAS metatask xmmselect allows them to interactively define source and background regions (via ds9) and to run backscale on the fly. ...

5. The Browne & March? Effect
... The BM effect causes low-luminosity blazars (particularly BL Lacs) to be missed in surveys because the apparent luminosity of the non-thermal nuclear source does not exceed that of the host galaxy by a large factor. ... Browne (1995). ... In addition to these objects, a large fraction of the newly-identified BL Lacs in our sample (10 of 22; see Table 5) have been so classified only by virtue of our usage of the expanded March? et al.

11. Finding definitions in the source
The HyperNews Linux KHG Discussion Pages . Forum: The Linux Kernel Hackers' Guide . Re : Linux SMP Scheduling (Angela) . Date: Mon, 16 Mar 1998 16:34:54 GMT . From: Felix Rauch < rauch@inf.ethz.ch > . The definition of NO_PROC_ID can be fount by, e.g., the following command: . find . -name "*.[ch]" -print | xargs grep NO_PROC_ID | grep #define . (assuming you are in the Linux-source-directory). This will show that NO_PROC_ID is defined as follows: . #define NO_PROC_ID 0xFF .

12. Study of radio spectra and variability of GPS sources
... The results of long-term monitoring of Gigahertz-Peaked Spectrum sources were found the statistically significant differences (0.05 significance level) in the high-frequency spectral index distribution between subgroups of galaxies and quasars. ... This can mean that the electron energy distribution for GPS galaxies is steeper than for GPS quasars. ... The first area corresponds to GPS-quasars that have statistically larger value of redfhift, second area corresponds to GPS-galaxies. ...
