The goal of this paper is to present the results of a preliminary analysis of the extended infrared (IR) emission by dust in the interstellar medium (ISM) of the Large Magellanic Cloud (LMC). We combine Spitzer Surveying the Agents of Galaxy Evolution (SAGE) and Infrared Astronomical Satellite (IRAS) data and correlate the infrared emission with gas tracers of H I, CO, and HЮБ. ... We construct maps of the temperature of large dust grains. ...

Presented on Tuesday, January 7, 2003 . We construct a detailed longitude-velocity diagram through the actual midplane of the Galactic H I disk. The Galactic midplane definition is based on single-dish sky surveys, and the detailed l-v slice ( Fig. 1 ) is extracted from the Canadian Galactic Plane Survey ( CGPS ; Taylor et al. 2003 ). ... Note: other slices offset from this one were not shown in the AAS poster for lack of space, but they are available here . ...

The Ryle Telescope was used for some years for monitoring variable sources (in addition to its role in source-surveys related to the Sunyaev-Zeldovitch studies). The instrument is now transformed into the "AMI large array": see the AMI pages for details. ... The rebuild took place between 2006 June and mid-2008; between these dates there is no useful data available. ... For some sources there are many plots, organised by date: . ...

The MRC was re-issued in 1990 with the original B1950 coordinates supplemented by J2000 values, and an additional cross-reference flag `J' added to denote (extended) sources imaged at 843-MHz by P.A. Jones. ...

. ATLAS is a project to image seven square degrees of sky, in two fields (CDF-S and ELAIS-S1), at radio wavelengths, to an rms of about 15 Jy, making it the widest deep radio survey aver attempted. The fields are chosen to cover the Spitzer Wide-Area IR Extragalactic Survey (SWIRE), and the radio images cut through the dust, to trace the cosmic history of AGN and star-forming galaxies.

... The three optical trains for the cameras, and the pupil reimaging system, are mounted on a wheel, accurately driven by an external motor. ... The low-resolution spectroscopic mode uses the wide field camera and a suitable set of grisms and order sorting filters that are inserted in the parallel beam after the pupil. ... One of the five grisms can operate at four different orders, depending on the filter selected on the first filter wheel that acts as order sorter. ...

When using a large number of Virtual Hosts, Apache may run out of available file descriptors (sometimes called file handles if each Virtual Host specifies different log files. ... Unix operating systems limit the number of file descriptors that may be used by a process; the limit is typically 64, and may usually be increased up to a large hard-limit. ... If you system falls into 1 or 2 (above), then increase the file descriptor limit before starting Apache, using a script like #!/bin/sh . ...
