blackant.net: other: docs: benchmarks: raid and volumes Disklabels: pentium wd0, pentium wd1, athlon wd0, athlon wd1 (note: fstype was changed as appropriate between '4.2BSD', 'ccd', 'RAID', 'vinum'). In other words, if wd0 = 9000 kb/s, wd1 = 11000 kb/s, and ccd = 15000 kb/s, then the average is 10000 kb/s and ccd is 1.5 times faster than that average. If redundancy is not needed, ccd should be considered as it outperforms both vinum and raidframe. www.blackant.net /other/docs/benchmarks/crv-fs.php   (690 words)

Butterfly spectrograph for LIBS / LIPS - laser induced spectroscopie,plasma analysis,breakdown spectroscopy Therefore echelle spectrographs generating a two-dimensional spectrum geometry coupled with CCD array detectors are particularly suited. A general problem, when measuring broad range LIPS spectra with a large CCD detector, is the intensity dynamics not only between single lines, but also the partially strong reduction of the signal-to-noise ratio from the visible to the VUV/UV range. It is a spectroscopic challenge that under certain conditions using sufficiently high linear dispersion of the spectrograph the continuum is spread enough, so that the usage of an ICCD camera is not necessary. www.ltb.fta-berlin.de /butterfly.html   (527 words)

[No title] The value of minus-one (-1) means that the CCD is not to be flushed at all when idle. The CCD will be brought back to its operating temperature automatically when the power is turned on. The information is as follows: CCD temperature: The temperature of the CCD Cryogenic temperature: The temperature of the cryogenic cooling system Controller temperature: The temperature of the CCD controller Instrument temperature: The temperature of the instrument Servo heater power: The power being applied to regulated the CCD temperature. www.as.utexas.edu /mcdonald/computer/ice-v2-ccd-controller   (2626 words)

Variable Star photometry: variable lightcurves and identification For this part, you will be using the CCD (charge-coupled-device) camera on the telescope in the dome on the roof.   The CCD is similar to the detector that’s inside your digital camera (or your video phone), but a little more expensive because it’s been designed to give a very uniform signal and be sensitive to very faint objects. Once you have the star centered, use the CCD control software to set the exposure to “focus”. www.physics.brown.edu /physics/labpages/ph0022lab/manual/VariableStarphotometry4.htm   (666 words)

Answer to what the star pattern is   (Site not responding. Last check: ) This is not something we are going to worry about degrading the images taken with the CCD as I did this on purpose. This image is a 0.1 sec flat field taken through a V filter, but the count rate of this image is 15000+ counts per second. And it is nothing the astronomer needs to worry about unless he is imaging REALLY bright objects in which he has to have very short exposure times. astroa.physics.metu.edu.tr /tug/ccd/answer.html   (187 words)

Eigenbau einer CCD Kamera mit Luftkühlung am Schmidt-Cassegrain C8 Eigenbau einer CCD Kamera mit Luftkühlung am Schmidt-Cassegrain C8 Eigenbau CCD-Kamera CB245 am Schmidt-Cassegrain C8 Im Frühjahr 1995 viel mir das exzellent aufbereitete 'CCD Camera Cookbook' von Berry, Kanto und Munger in die Hände und ein Projekt war geboren. Mit der kleinen TC211 wurden die ersten Erfahrungen gesammelt, aber schon nach 2 Monaten mußte es die TC245 sein. Auf Empfehlung von Dirk Langenbach wurde der Transistor Q7(Schaltplan: CCD Camera Cookbook S.74) entfernt und gebrückt, die Temperaturdrift ohne nachteilige Begleiterscheinungen dadurch gesenkt. www.inastars.de /eigenbau.htm   (499 words)

Dr. Dobb's | Celestial Programming With Turbo Pascal | July 22, 2001 This article describes a project using a CCD camera and Turbo Pascal to deliver a digital image to a PC where it can then be displayed, stored, and processed. CCD cameras have a linear response to faint light signals, eliminating a shortcoming of conventional photographic emulsions, called reciprocity failure, where the exposure time required to record faint light sources grows exponentially. The signals from the light-sensitive cells are processed by the CCD camera and are output in the form of a fl-and-white NTSC television signal. www.ddj.com /184408571?pgno=5   (4378 words)

FLIPS: User's Manual The gaps between the CCDs were properly measured with shifted star fields on the mosaic and then corresponding relative offsets were entered as parameters of this imcompose module. The last two numbers are for a overscan correction along the X axis, something rarely needed, that's what these last two numbers are set to the same value: there won't be a correction based on the level of the top area of the image. This module only works on one CCD of the mosaic at a time, but it is very easy to create a script that launches the command for the 8 CCDs of the mosaic. www.cfht.hawaii.edu /~jcc/Flips/Manual/manualflips.html   (8226 words)

Guide to Minor Body Astrometry The CCD that is right for you depends on your computer system and on how much you want to spend. Most CCD fields tend to be rather small (a few tens of arcminutes wide) and this has in the past precluded the use of traditional standard astrometric catalogues. This has a sufficient density of comparison stars for most purposes, but the positions are known to be somewhat iffy in regions that were near the edges of the plates scanned to produce the catalogue. www.cfa.harvard.edu /iau/info/Astrometry.html   (7533 words)

Kodak cuts 15,000 jobs & buys Chinon: Digital Photography Review Kodak has today said it would cut as many as 15,000 jobs and take charges of up to $1.7 billion over the next three years as it works through a painful shift toward digital products and away from the waning film market. The photography company, whose shares soared to their highest level in seven months in early trading, also announced an 83 percent decline in fourth-quarter net income. On Thursday, the Rochester, New York-based Kodak said it would cut 12,000 to 15,000 jobs worldwide, or about 20 percent of its work force, including 2,500 to 3,500 this year. www.dpreview.com /news/0401/04012201kodakjoblosses.asp   (1498 words)

[No title] The section must map directly to the specified data section through the binning and CCD to image coordiante transformation. Normally this would be the physical size of the CCD unless drift scanning is done. It is highly recommended that controllers read out all pixels with the same summing in which case the size of the CCD section will be the summing factors times the size of the data section. iraf.noao.edu /projects/mosaic/imagedef/mosaic/MosaicV1.dic   (3388 words)
