... Stellar Evolution is driven entirely by the never ending battle between Pressure and Gravity . As imbalances are reached, the star is driven to find a new Energy source. ... Pressure and gravitational forces are equal, the star is stable and its core is sufficiently hot to fuse Hydrogen into Helium More about main sequence stars . ... The luminosity generated by the core fusion of Helium into Carbon is far greater than the shell luminosity associated with the fusion of Hydrogen into Helium. ...

... The absolute flux calibration of NICMOS will be calculated from observations of standard stars with known flux distributions F( ). ... In order to expand the set of IR standard stars in the appropriate flux range for NICMOS, M. Rieke, R. Thompson, and collaborators at the University of Arizona are making photometric observations of solar-analog stars, which will be used to normalize the solar spectrum to the observed IR magnitudes. ... Relative flux references accurate to 1.5% for standard...

The sp ectra taken with the 6 m telescop e are used to determine the radial velo cities and pro jected rotational velo cities for 32 newly discovered magnetic CP stars. ... Our observational data -- Zeeman sp ectra taken within the framework of the program for the search for new magnetic stars can b e used for determination of radial velo cities (V r ) and pro jected rotational velo cities (v e sin i). ... Our new sample features more distant ob jects. ...

Next: Reduction procedure Up: Extinction and transformation Previous: Strategy . Standard stars can be included in the extinction solution, if one is careful. The problem is that there are usually appreciable ``conformity errors'' due to mismatch between the instrumental and the standard passbands [ 16 ]. ... Thus, it is wrong to assume that the transformation between the instrumental system and the standard system is exact, even if there were no measurement error in either system [ 1 ]. ...

multi-rsh is a perl script which runs the same command on multiple machines, in parallel, and provides reasonable, adjustable timeouts for those machines which fail to answer. Both standard output and standard error are returned through the same channel, and all output has the hostname prepended to each line. Multi-rsh must be run as root (remote jobs can be set to run as any user, see Options below). ... Neither form allows you to directly pass input to the remote programs. ...

... Standard magnitudes can only be computed for the U, B and V filters and hence the only standard colours that can be calculated are U-B, B-V and U-V. An important point to note, is that these standard colours can be computed using the following instrumental colours - U-B, B-V, U-V, (UVW1-U), (UVW1-B), (UVW1-V), (UVW2-B) and (UVW2-V). ... The program loops through these colours and if the relevant instrumental magnitudes are present computes the standard magnitudes and standard colour. ...

Next: THE SOURCE LIST Up: Spectral-Line Observing at AO Previous: THE RADAR BLANKER . ... You also need to decide how you want this correction to be applied - to the center of each correlator board or to the four boards as a whole (thereby preserving the topocentric frequency offset between the boards). Typically, this choice depends on whether each board is centered on a known spectral line, or if you are doing a search in velocity space for an object. ...

The original files with the data were in different formats. ... Such files were named "standard data files" and linked to the database. They can be easily transformed to any desirable format by a code. Here we present two simple computer programs of this kind. ... When running the code, you can specify columns in the output file: wavelength, energy (eV) or wavenumber (cm -1 ) as the first column, and complex refractive index or dielectric function as the second and third columns. ...

... The pinhole simulation program is a computationally and memory intensive task. ... A parallel version was developed instead, to enable distributed processing on a cluster of workstations. The program makes use of the Message Passing Interface (MPI) standard for parallel processing, implemented as an API (Application Programming Interface) to the Local Area Multicomputer (LAM) programming environment developed at the Ohio Supercomputer Center. ...

... Data Handling and Products > Data Reduction FAQ > The spectrum of my MOS flux standard star is shifted in wavelength by several pixels. Why is that and how can I correct for it? ... Observing with ESO Telescopes . ... The shift of the flux standard spectrum is caused by a combination of bad centering within the slit and possible wavelength calibration issues. To align the spectrum to the tabulated flux, use the parameter --resp_shift in vmmosscience when determining the response curve. ...
