1. jun12-dec12 sysperf,pnterror
Calibration data from jun12 through dec12 was used to look at the system performance and pointing errors of various receivers. 06jun12 - model 18 installed. ... Prior to this, little power was getting into polB. 430 dome data used was after 19oct12. 28oct12: new sbn receiver installed . ... they had an exceptionally large pointing error for this receiver (say > 60 asecs) . ... The offsets for the other receivers are then computed relative to sbn using 2 or 4 sources.This was done back in apr-may12. ...

2. 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 . ...

1000 of these sources, however, remains a mystery; these are the so-called unassociated gamma-ray sources, with no known astrophysical counterpart at any other wavelength. While many LAT unassociated sources likely belong to known classes of objects (e.g. pulsars), a more exotic origin for some of these sources is also possible (e.g. dark matter annihilation). ... These results will aid further studies and follow-up observations of LAT unassociated sources. ...
