... 2011 September 7 . SDSS J102915+172927: A Star That Should Not Exist . ... Explanation: Why does this star have so few heavy elements? Stars born in the generation of our Sun have an expected abundance of elements heavier than hydrogen and helium mixed into their atmospheres. Stars born in the generation before our Sun, Population II stars , the stars that created most of the heavy elements around us today, are seen to have some, although fewer, elements heavier than H and He. ...

... J102815: A Star That Should Not Exist . ... Stars born in the generation before our Sun, Population II stars , the stars that created most of the heavy elements around us today, are seen to have some, although less, elements heavier than H and He. Furthermore, even the elusive never-seen first stars in the universe, so-called Population III stars, are predicted to have a large mass and a small but set amount of heavy elements. ...

... Archives . ... It refers to the spread in the measured energy of an incoming photon, and even astronomers often stumble over what it is and what it contains. ... The R edistribution M atrix F ile (RMF) is, at its most basic, a description of how the detector responds to incoming photons. ... The process of measuring the energy introduces a measurement error, which is encoded as the probability that incoming photons at energy E are read out in detector channels i . ...

Next: Mission Element Points-of-Contact . Previous: Mission Operations Data Transfer . ... Each mission element should ensure that their contact information remains current and notify the RSOG of any changes. ... Non-RSOG mission elements will also use the "dit" list to notify the RSOG (and all other mission elements) of unexpected events that may impact operations elsewhere, e.g., if a tracking station discovers that the spacecraft is in an unexpected configuration. ...

Instrument Science Report WFC3 2005-23 Optical Properties of Blocking Glass in the WFC3 IR Channel D.F. Figer & S. Baggett August 16, 2005 ABSTRACT RG830 and IR80 will be used as the optical blocking glass in the WFC3/IR channel to ensure that short-wavelength (optical) light does not reach the detector. ... As can be seen, the transmission through RG830 is very low at wavelengths below about 760 nm, thus providing blocking at optical wavelengths. ... Characteristics of RG830 glass from Schott. ...

... The only event-driven pieces of software were the user interface Hermes, the display server GIDS and the GDS server. ... Event-driven tasks are fundamentally different from procedural tasks. ... Using this event handling, a collection of routines has been built, which allows the programmer to construct a graphical user interface for a task. ... These are the events associated with user input keywords and one other event which is generated when a task is resumed after it was pausing. ...

To construct two-dimension distribution of minor planets user should specify elements/ parameters/ function that will be plotted as abscissas and ordinates. In three-dimension case one should add to them the element plotted on Z axis. ... Though you may choose elements plotted along different axes at will, often there is good reason to plot such elements as a, n, or n" along X axis (two-dimension distributions) and to plot them along Y axis in three-dimension case. ...

Programs to generate color spectra ================================== These programs were developed to produce realistic color spectra from digital data. ... The distribution here contains the original source code for colorspec and solar in C, and a version of solar written in Fortran. ... It will produce a color spectrum of any digital spectrum. ... The 800x50 image solarflux.ppm was generated by colorspec and the file fluxatlas.dat, a reformatted NSO Solar Flux Atlas in the data directory. ...

... The fitting package in STSDAS (Space Telescope Science Data Analysis System) relies on two basic techniques (one linear and one non-linear) for fitting functions to data. ... Results show that both methods may generate biased coefficients (at the ~few percent level), and over or under-estimate error bars (at the ~10 percent level), in particular from low signal-to-noise data. ... Function coefficient errors are computed directly from the covariance matrix. ... Abscissa is signal-to-noise. ...
