... You can boot Linux either from a floppy or from the hard disk. ... When booting Linux from a floppy disk, the boot sector contains code that just reads the first few hundred blocks (depending on the actual kernel size, of course) to a predetermined place in memory. On a Linux boot floppy, there is no filesystem, the kernel is just stored in consecutive sectors, since this simplifies the boot process. ... For example, when I boot, I it looks like this: љ љ љ љ LILO boot: Loading linux. ...

... Finding Stars . ... Handling Bad Pixels . ... The guide camera image controller can control one or more guide cameras. ... Each time the camera is read, the image is automatically saved to a fits file on a shared disk. ... Cameras that have bad pixels require "bad pixel maps" in order to find stars, centroid or even compute statistics for the image. ... View this image (for instance in NIH Image) and determine an upper and lower cutoff; pixels whose values are outside of this range are considered...

... Cylinder-Head-Sector (CHS) form, or physical form, addresses each sector with a (cylinder, head, sector) triplet. ... The number of cylinders, heads per cylinder ("heads"), and sectors per head ("sectors") is called the "disk geometry". ... Linux does not use the BIOS for anything except to determine the disk geometry. ... Both DOS fdisk and Linux fdisk expect these values to agree. DOS fdisk obtains the disk geometry by querying the BIOS; Linux fdisk obtains the geometry by querying the kernel. ...

... Triggered Star Formation . ... It is now well established that massive stars in star forming regions can trigger next generation of star formation. ... The young stellar objects (YSOs) in star forming regions have been identified using the near-infrared (NIR) and mid-infrared (MIR) observations. ... The age of YSOs, the morphology of the regions and the global distribution of YSOs indicate that the star formation can be triggered by either (RDI/ CC) of the processes. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...
