The srcinten task provides PROS users with a tool to compute count rates for point sources in the ROSAT High Resolution Imager (HRI). ... Corrected upper limits are cited at locations where the count rate falls below the source detection threshold. ... Srcinten is a new PROS task that computes and applies the above correction factors to the net counts in a user-specified aperture. ...

The hot side of the TEC is bonded to the CCD housing baseplate; hence with fixed TEC current, the CCD housing should track closely the detector temperature under Side 2 operations, and this can be seen by the excellent correlation between the dark rate and the housing temperature ( ISR STIS 2001-03 ). ...

Authors: V.A. Marsakov , Yu.G. Shevelev , . Journal: 1988, Astron Zh. ... Absolute magnitudes, metallicities, effective temperatures, surface gravities, distances, and tangential velocities are calculated for 5498 F stars with homogeneous data on uvby photometry and proper motion, and placed within 80 pc from the Sun. Components of space velocities, eccentricities of galactic orbits, perigalactic and apogalactic distances, and maximal remotness from galactic plane are presented for 1787 stars. ...

... English (Australia) . ... New thermal images from ESOтАЩs Very Large Telescope (VLT) and other ground-based telescopes show swirls of warmer air and cooler regions never seen before within JupiterтАЩs Great Red Spot. The images enable scientists to make the first detailed weather map of the inside of the giant storm system. One observation illustrated by this image is the correspondence between a warm core within an otherwise cold storm system and the reddest colour of the Great Red Spot. ...

The HAWAII detector is an array of HgCdTe photodiodes whose junction capacity collects a charge proportional to the number of photons that they receive. ... The array detector is read by an electronic system based on the controller developed by the CCD Working Group of TNG, modified to speed up the read-out time, and on a fast 16 bit conversion board (2 Mb/s). ... The signal read on each pixels is buffered by electronics located on the same board that hosts the detector. ...

Next: Pressure Up: Additional information Previous: Additional information . ... Although the ESO Archive standard is to record temperatures in kelvins, this is often inconvenient. ... Therefore, if the temperatures are not in kelvins, the appropriate units should be provided in the table file (if temperatures are in a column), or as a comment. ... If filter and detector temperatures are otherwise regulated or recorded, it may still be useful to record DOMETEMP in the data file as a Real*4 column. ...

... Electronic Raman scattering in the single - CuO 2 layered superconductor Tl 2 Ba 2 CuO 6+ d . ... Electronic Raman scattering in Tl 2 Ba 2 CuO 6+ d (Tl-2201) has been investigated in order to test whether the scattering cross section in high-temperature superconductors depends on the number of CuO 2 planes, i.e., sheets specific details of the Fermi surface. ... The peak in the B 1g symmetry component of the scattering intensity is found at 460 cm -1 ( T c = 90 K), or 430 cm -1 ( T c = 80 K). ...

Electronic Catalogue of Comets "Halley" . ... In this paper we give a description of the Electronic Catalogue of Comets "Halley", which makes it possible to calculate the evolution of the orbits of comets, to visualize orbital motion, to determine the circumstances of a comet's close approach to planets within a given time interval, as well as a number of other opportunities. ...

... While a basic pile-up correction implementation is available, this feature is not currently being maintained. arfgen provides a feature for correcting for the loss in detection efficiency due to over-lapping events occuring within the same frame. ... He provides formulae for flux loss for each of the four patterns accepted by the on-board detector electronics, given the pattern morphology and contributions of each pattern to the incident photon spectrum. ...
