... We report on our ongoing project ``Infrared Study of HII Regions Associated with Small Clouds.' ... These IR data, combined with optical imaging (which will be obtained from the IAC-80 telescope), IRAS survey maps, and existing CO observations of the associated clouds, will allow us to undertake a detailed investigation of the gas-to-dust mass ratio, initial mass function and the star-formation efficiency in these complexes. ... CHECKPSF: check the PSF (Point Spread Function) model, . ...

Alfa was reinstalled in the dome in sep11. Calibration runs were done in sep11,oct11 to measure any pointing offsets. ... After looking at the results, the alfa model was updated to correct for the constant offset term. ... The heiles calibration scans were used to measure the pointing error. ... page 1: measured pointing errors: . ... The pointing errors are: . ...

... Fit the ring around the equator and then change its inclination from 0 degrees (equatorial orbit used by geosynchronous satellites) to 28.5 degrees (space shuttle orbit) to 51.6 degrees (space station orbit) to 90 degrees (polar orbit used by spy satellites). by Rob Landis, Space Telescope Science Institute . ... With so many satellites now in orbit, it is likely that you have seen an artificial satellite zipping across the night sky. ... http://www.amsat.org/amsat/ftpsoft.html . ...

Imaging CMB Anisotropies with CAT Joanne C. Baker 1 Mullard Radio Astronomy Observatory 2 , Cavendish Laboratory, Madingley Road, Cambridge CB3 0HE, U.K. The Cambridge Cosmic Anisotropy Telescope (CAT) has recently made the first detailed image of primordial anisotropies in the cosmic microwave background (CMB) radiation at 15 GHz. Preliminary results from CAT observations of a second 2 ffi \Theta 2 ffi field are presented here. ... 30 ffi ). ...

... The two-faced Whirlpool Galaxy . Probing a galaxy's dust structure serves as an important diagnostic tool for astronomers, providing invaluable information on how gas and dust collapse to form stars. ... The image at left, taken in visible light, highlights the attributes of a typical spiral galaxy, including graceful, curving arms, pink star-forming regions, and brilliant blue strands of star clusters. ... The visible-light image captured only some of the light; dust obscured the rest. ...

Next: The buffer cache Up: Memory Management Previous: Sharing swap spaces with . Some people will tell you that you should allocate twice as much swap space as you have physical memory, but this is a bogus rule. ... So, in order to allocate swap space, you just need to subtract the size of your physical memory from the total memory needed, and you know how much swap space you need. ... Linux uses swap space somewhat aggressively, so that as much physical memory as possible can be kept free. ...

Originally there would have been no Lunar Module.The Apollo CSMтАЩs origins go back to the 1950s, and it was intended to be a multi-purpose vehicle for all kinds of missions in Earth and lunar orbit. ... Months later Apollo 10 flew to lunar orbit in May. ... Dear James, to get the entire Apollo spacecraft (Command/Service Module and Lunar Module) to orbit the Moon took a three stage Saturn 5 launch vehicle. ...
