The CCDs and their associated signal chains have readout noise levels (in the absence of signal shot noise or interference) of approximately 5e - . The analog-to-digital converter is highly accurate, and makes virtually no contribution to the read noise, other than the normal information loss caused by digitization of the signal. ... Note that all calculations of sensitivity in this manual assume gains of 7 and 14 for two gain channels, choices very close to the measured gains. ... 0.41 . ...

As the fifth part in our series of papers on galaxies in the "zone of avoidance" (ZOA) of the Milky Way we present 1346 new galaxy candidates discovered during a systematic search on Palomar Observatory Sky Survey (POSSI-E) red-sensitive prints. ...

This source is hiding behind our Galaxy at a distance of ~18 Mpc, located at a galactic latitide of 0 degrees. ... As we look towards longer wavelengths, 60 micron, to try and penetrate the Galactic Plane, we still see confusion from galactic sources. ... If the image seems some what confusing that is because the MOST is a continuum radio telescope and when it looks in the direction of our Galaxy it detects radiation from sources within our Galaxy and from sources that may lie behind our Galaxy. ...

The small variations in distance to the individual Cepheid variable stars in the Cloud are negligible compared with the much larger distance to the SMC. ... In this way Cepheid variable stars can be used as one of the 'standard candles' in the Universe that act either as distance indicators themselves or can be used to calibrate (or set the zero point for) other distance indicators. ...

. Comment on J1146-3328 . The derived position here is about 20" from that of the PMN survey position (Griffith & Wright 1993). The source is only detected on the shorter baselines and is probably resolved, although some smearing may be caused by the large position offset. VLBApls home page . Last modified: 16 Oct 2000

... Teeny-weeny cold HI clouds in the diffuse ISM . I will discuss the lowest-column density cold HI clouds, originally discovered by Braun Kanekar (2004) and recently confirmed by Stanimirovic Heiles (2005) using the Arecibo telescope. These cold clouds have HI column densities of ~10 18 cm -2 , below an observational lower limit derived by Heiles Throland (2005), and also below tiny-scale-atomic clouds detected by VLBI and time-variable profiles against pulsars. ...

. This shows the largest of the newly detected graben found in highlands of the lunar farside. The broadest graben is about 1,640 feet (500 meters) wide and topography derived from Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) stereo images indicates they are almost 66 feet (20 meters) deep.
