All stars derive their energy through the thermonuclear fusion of light elements in to heavy elements. High temperatures are required so that the mutual electrostatic repulsion of the protons in each fusing atomic nucleus is overcome. ... Elements with more protons in their nuclei require higher temperatures. ... This sequence is now shown in the animation below. ... First Step of the Proton-Proton Chain Narration . Second Step of the Proton-Proton Chain Narration . ...

Next: Particle Background Rejection Up: Detection Efficiency Previous: Front Illumination . ... The method requires that the CCD substrate be etched from the rear towards the depletion layer boundary. The device can be illuminated through this rear surface, which has a much thinner dead layer than the electrode side. ... The corresponding detection efficiency data are presented in Figure 7, and compared with the predicted data for a 20 m thick depletion layer. ...

... Do not exceed safe floor loads. An 18-inch clearance is required between top of storage and smoke detectors. ... A 3-foot minimum clearance must be maintained between stored materials and unit heaters, radiant space heaters, duct furnaces, and flues. ... Extensive regulations (OSHA & NFPA) exist which govern the use, inspection, and maintenance of overhead cranes, hoists, and slings. ... safe clearance must be maintained for the safety of personnel; . ... signed records must be maintained; . ...

. I worked on the bug with stsdas help, with no success. I then returned to trying to figure out the difference between the old and new drizzlepac coordinate mapping. It turns out the old drizzlepac was using its internal mapping code, so I forced it to use the wcs mapping code instead.But that did not resolve the difference. Search . Pages . Front Page . Weblog .

Microsymposium 34, MS058, 2001 ANOMALIES OF THE MOON'S THERMAL EMISSION IN THE IR SPECTRAL RANGE (10.5 - 12.5 micron). ... Sternberg State Astronomical Institute, Moscow, 119899, Russia, pugach@sai.msu.ru Summary: New satellite measurements of the lunar-surface radiation temperature were used to construct the spatial angular function of thermal radiation of the Moon in the infrared (10.5-12.5 micron) spectral range. ... These thermal anomalies are observed only in the limited range of phase angles. ...

... We give evidence that lower pressure model chromospheres can alos reproduce the Balmer line profiles, but give Lyman surface fluxes overestimated by more than an order of magnitude. ... We obtain the Paschen lines in emission and Paschen decrements as large as 41 for Pa$_{\beta}$. ... Formation of all Hydrogen series is collisionally controlled and takes place in a rather thin layer at the top of the chromosphere (Balmer, Paschen, and Brackett) or in the transition region (Lyman). ...

... SDFITS is a FITS binary table convention for the interchange of single dish data in radio astronomy. ... In October of 1989 a meeting of interested representatives of many of the world's radio-astronomical observatories was held in Green Bank, West Virginia, to consider the creation of a standard data transport and interchange format for single dish (i.e. non-synthesis) radio astronomy data. ... A set of required (CORE) and recognized but not required (SHARED) column names were also agreed to. ...

Hide Zen home . ... Collecting more catalogues x2013; right now I would like to have catalogues like 2DF, RC3 . Allow the storage of SQL views in CAS. Arbitrary SQL queries from the user. My opinion is that's in the very future, since it requires the system to queue the queries, it requires the user quota system (of the user's data in the DB), and I guess it requires an additional (or more powerful) server. And right now we don't have any of these things x2026; . ... Zen, 2003-2007 ...
