... NICMOS data are represented by five arrays for each readout. ... Samples array. ... Each downlinked readout is always represented by these five arrays ( Figure 13.4 ). Multiple readouts in the same dataset (e.g., MULTIACCUM data) are represented by repeated sets of these five arrays ( Figure 13.5 ). ... For data where multiple samples of the array were obtained during the integration, the samples array denotes the number of samples for each pixel in the corresponding science image. ...

... Two high school students from Texas and Louisiana are the winners of the 2012 Priscilla and Bart Bok Awards for their astronomy projects presented at the Intel Science and Engineering Fair in Pittsburgh, Pennsylvania in May. The awards were presented on May 18 by the Astronomical Society of the Pacific (ASP) in partnership with the American Astronomical Society (AAS), supported by funding from the National Science Foundation (NSF). ... The Bok prize is named for Bart and Priscilla Bok. ...

The Large and Small Magellanic Clouds set the Milky Way's dark-matter halo in motion as they orbit. ... The Milky Way is at center, and the position of the Sun is about half way out in the picture of the galaxy along the line marked X. The crosshatched area represents the warped hydrogen layer. The looping line represents the 1.5-billion-year orbit of the Magellanic Clouds (shown as a yellow bead at the satellites' present position). ...

ABSTRACT: Both previous radiomessages for aliens, Arecibo 1974 and Evpatoria 1999 (see http://ebe.allwebco.com/Science for details) were the logical ones and represented the binary stream of FM information, which should be arranged into two-dimensional forms to perceive by eye-like sense-organ. ... So, I suggest to implement the 1st Theremin Concert for Aliens from Arecibo or Evpatoria Radar facility. ... The theremin was invented 80 years ago, in 1920 by Leon Theremin. ...

Arecibo Proposal No. ... And I guess the primary one-dimensional message is more understandable by unfamiliar aliens and the music is the most universal expression of intellectual activity by means of one-channel ear-like radio link. ... So, I suggest to implement the 1st Theremin Concert for Aliens from Arecibo or Evpatoria Radar facility. ... There were four Messages from Earth to proposed aliens -- two material (Pioneer Plaque and Voyager Record) and two ethereal (Arecibo-1974 and Evpatoria-1999). ...

... In combining the data, it is assumed that the low resolution image better represents the short spacing data, whereas the high resolution best represents the fine structure. ... Key: out The output image. ... Key: factor The flux calibration factor. ... In practise, the calibration may not be perfect, and an extra calibration factor will be required to align the flux scales. "factor" gives the factor to scale the low resolution image to put it on the same flux scale as the high resolution image. ...

... About ISSP . ... MOBILE INSTALLATION FOR PRODUCING OF . A THERMALLY SPLINTERED GRAPHITE SORBENT . ... The installation and technology elaborated in the ISSP for producing of a thermally splintered graphite sorbent (TSGS) enable obtaining absorption coefficient values from 60 g/g to 100 g/g. Moreover, the TSGS is an absolutely hydrophobic material and collected oil products may be used as high effective fuel. ... The produced installation is tested on the Т?East-WestТЛ oil-pipe line. ...

... The upward propagating HF wave is reflected at a particular height. ... The instabilities seen by the radar shortly after the HF is turned on can be divided into two types according to the degree of sophistication required in the model describing the response to the E field of the HF wave. ... The first kind occurs at a particular height determined by k vector and frequency matching conditions on the HF wave, the low and high frequency plasma waves, and the radar EM wave. ... Incoherent Scatter . ...

... Next: An IRAF-Independent Interface Up: Software Systems Previous: A New PROS . ... We present a high-level representation of the packages and tasks within IRAF/PROS. ... We have produced a high-level overview of PROS. ... The incremental stages were the short-term goals: a project overview diagram (i.e., an organizational diagram of software modules); high-level diagram (i.e., a bubble diagram of each module in the system); and unifying element tables (i.e., tables of task vs. software attributes)....

Stellar Clusters are very useful laboratories for empirically studying stellar evolution. ... All cluster stars are at the same distance . All cluster stars have the same physical age . ... CM diagram Young Cluster In this case we see the Main Sequence fully represented. The blue dots represent massive stars with short main sequence lifetimes. ... Thus, identifying the most massive star which is still on the main sequence is an effective means of determining the age of a stellar cluster. ...

... Fitting the observed dependence includes calculations of the polarization cross-sections averaged over particles orientation and size distribution, their normalization and the comparison of obtained dependencies with Serkowski's curve representing observational data for a chosen star. ... Variations of the polarization factors with wavelength are shown in Fig. 16 for homogeneous spheroidal particles with PF orientation. ... The distinction between prolate and oblate spheroids is also clearly seen. ...
