... The active time at each angular bin is the sum over frames of the active time contributions from all CCD pixels, within the node-specific telemetry window, which overlap the surface of the bin. ... The active time, per frame, of a normal pixel is the full frame integration time multiplied by the node-specific fractional exposure; bad pixels contribute no active time. ... If an event is rejected for this reason only, then its pixels remain normal in the exposure map. ...

This diagram illustrates a floating image that overlaps the borders of two paragraphs in normal flow: the paragraph borders are clipped by the non-transparent parts of the image. ... A left-floating image causes the final three lines of the upper paragraph to float along its right side. It causes the first three lines of the following paragraph to do the same, and the remainder of that paragraph flows normally. The paragraph borders shine through the margin area of the image box. ...

... Do not warn when variables are not explicitly declared. ... Do not check if a variable has been initialized before being used. If a variable is not in a DATA, COMMON, PARAMETER or SAVE statement, and if it is not a dummy subroutine argument, then Flint normally attempts to check that the variable is initialized before it is used. ... By default Flint warns if subroutine or variable names are longer than 8 characters, or if they contain underline or dollar characters. ...

Next: Echelle Reduction Up: No Title Previous: CCD-Commands Summary . The reduction of CES spectra is, especially for point sources, very straightforward, and the general instructions given in Chapter 6 for the standard reduction of spectra are fully adequate. ... As far as the data reduction goes, the main difference between Reticon and CCD is the data format. Since the Reticon is a one-dimensional array, no attention has to (can) be paid to the extraction of the object spectra. ...

... Suppose that a NS having a rotational magnetic   luminosity forms a binary system (with semi-major axis a ) with a normal star losing matter in the form of stellar wind (with a loss rate ). ... This means that while deriving the formula for a cavern in the general case, we must take into account the proximity of the normal star. ... It follows from the symmetry considerations that at the anterior point of the cavern (i.e. the point closest to the normal star), . ... If , the cavern is closed. ...

... SFIT is a general-purpose code designed to optimize theoretical stellar spectra to an observed spectrum. ... While the programme expects input from "stdio", it is more natural to save commands in a file (eg "sfit_input") and run the code simply by . ... If the spectra to be fitted have a filename "star_spectrum", then the best fit spectrum will be written out, together with the renormalized input spectrum, to a file called "star_spectrum.fit". ... sets up model spectrum grid (and for 2nd star) . ...

... Normal cloud bottoms are flat because moist warm air that rises and cools will condense into water droplets at a very specific temperature, which usually corresponds to a very specific height. ... Planetary Nebula Project . ... The North America Nebula in Infrared . ... Red stars are cool, with surface temperatures of around 3,000 kelvins (K), while blue stars are hotter and can have temperatures over 30,000 K.

These observations are aimed at fully charactering FORS1 photometric system (UBVRI zero-points, color-terms and extinction coefficients) for the Tektronix 2048x2048 pixel CCD (24µm px) . To this aim, the two Landolt/Stetson photometric fields SA95 and SA101 will be observed on a number of epochs and at different airmasses during February and March 2007. ... SA101 . ... OBs for SA101 have to be observed during evenigh twilight (exceptions are expected for the second half of March) . ...

You can also sort on a specific part of a field if necessary. To define which part of a field to sort on you give the position in the field at which to start the sort followed by the position in the field at which to end the sort. The position at which to start the sort is given as the number of fields to skip followed by the number of characters to skip. ... tells sort to skip the first two fields and the first three characters of field 3. ...

ASTRONOMY DO LIRGs FOLLOW THE TULLY-FISHER RELATION? Veronica M. Torres, Adriana J. ColСn; Colegio San Felipe, Arecibo, Puerto Rico Research Mentor: Dr. Tapasi Ghosh, Arecibo Observatory, Arecibo, Puerto Rico The purpose of this research was to study the LIRGs (Luminous Infrared Galaxies) and see if they follow the Tully-Fisher relation. ... The Tully-Fisher relation states that the bigger the galaxy is, the faster it rotates. ... Also, the bigger the galaxy, the more is its luminosity. ...

... Star Atlas . ... stars . ... If neutron stars don't produce energy from fusion, like normal stars, how can they shine in visible light? ... Although it is true that neutron stars have, for the most part, consumed all their internal thermonuclear fuel, they tap into other energy sources to produce light. Indeed, neutron stars are remarkably "resourceful" and employ a variety of physical mechanisms to make themselves visible.A newborn neutron star is incredibly hot ? ... Atlas of the Stars . ...

... A simple Virasoro vertex algebra is rational (and -2 semisimple as well) iff its central charge is of the form c = 1 - 6(pppp ) , where p, p are relatively prime integers, greater than 1 (which are central charges of the so called minimal models). A simple affine vertex algebra Vk (g), attached to a simple Lie algebra g is rational (and semisimple as well) iff its level k is a non-negative integer. ... We call such f an exceptional nilpotent and such k an exceptional level. ...
