... 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 zero assumption often made is that the mass ratio distribution has a flat shape, that is binaries with a high mass ratio occur as frequently as those with equal masses. ...

Aims: We present an analysis of a galaxy (SAGE1CJ053634.78-722658.5) at a redshift of 0.14 of which the infrared (IR) emission is entirely dominated by emission associated with the active galactic nucleus. Methods: We present the 5-37 ЮМm Spitzer/IRS spectrum and broad wavelength spectral energy distribution (SED) of SAGE1CJ053634.78-722658.5, an IR point-source detected by Spitzer/SAGE. ... We compare the source with models of emission from dusty tori around AGNs. ...

Whilst no radio emission was detected from any of the targets, significant upper limits were placed on the radio luminosities that are below the luminosities of previously detected ultracool dwarfs. Combining our results with those from the literature gives a detection rate for dwarfs in the spectral range M7 тАУ L3.5 of тИ® 9%. ...

HI line flux (flux corresponding to the area under the 21-cm line profile) is generally expressed in converted in magnitude m21 according to the formula adopted in RC3: m21 = -2.5 log f + 17.40 where f is the area of the 21-cm line profile expressed in Jy*km/s (the constant is 16.6 if the flux is in 10**-22 W/m**2). Non-detections (or upper limits) are not stored in the database, therefore galaxies with no HI measurements available may either be too faint or not have been observed. ... HyperLeda . ...

DISCLAIMER: The larger the aperture, the more light a telescope will gather and the fainter the object you can see. Here is a range of magnitudes you might expect to see. Given excellent sky conditions and good optics, a well trained eye can sometimes add up to 0.8 magnitude to these values. Limiting Magnitude depends on much more than the instruments aperture. ...
