... To avoid possible misinterpretations and naming conflicts for keywords describing acquisition parameters, ESO has adopted a hierarchical keyword convention for this purpose using the keyword HIERARCH . Such keywords have the following syntax: HIERARCH domain level-1 ... level-n keyword = value / comment . where the domain always is ESO . ... Table: Levels defined for ESO hierarchical FITS keywords and the abbreviations used for the translations to MIDAS descriptor names . ...

Next: Stellar models Up: Introduction Previous: Photometry Contents . In a hierarchical stellar system, the separation between two neighboring stars is always much smaller than the separation of this pair from the next companion in the system, be it another pair or a single star. ... They are also numerically easier to handle than non-hierarchical systems, since each pair can be described with the standard orbital parameters, and each star with a small number of physical parameters. ...

A crucial aspect of 3D Monte Carlo radiative transfer is the choice of the spatial grid used to partition the dusty medium. We critically investigate the use of octree grids in Monte Carlo dust radiative transfer, with two different octree construction algorithms (regular and barycentric subdivision) and three different octree traversal algorithms (top-down, neighbour list, and the bookkeeping method). ... The total number of grid cells, however, depends on the geometry of the model. ...

We need simple numbering scheme, so that for any given point we could easily calculate the number of "pixel", this is what HealPix provides and lacks HTM. ... During Rtree queries the number of index blocks read is several times greater than during Q3C queries. ... But in Q3C scheme, as we showed before, the circle is segmented, so we extract from the database only a few percents more data than occur in the circle. ...

... The value of tile-size, NW , may be thought of as a sixth coordinate axis in the chirplet transform parameter space - TF-area. Including this sixth coordinate axis provides us with a hierarchical (multi-resolution) CCT. ... Various 2- D slices through the multiresolution CCT may correspond to useful tilings of the TF plane with true parallelograms (true to the extent that the DPSS define a truly rectangular region in the TF plane). ...

GJ 900 - a new hierarchical system with low-mass components E. Malogolovets, Yu. Balega, D. Rastegaev, K.-H. Hofmann, G. Weigelt Speckle interferometric observations made with the 6 m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences in 2000 revealed the triple nature of the nearby (d=19.3 pc) low-mass young (age about 200 Myr) star GJ 900. The configuration of the triple system allowed it to be dynamically unstable. ...

The Master Index acts as an observation catalog with references to Subsystem Indices, while the latter contain configuration information and references to the Data Tables. ...

There are still many open questions on galaxy formation and evolution, such as e.g. the predominance of hierarchical or monolithic processes in the galaxy formation or the temporal evolution of disk metallicity gradients. ... Chemical abundances of stellar populations of different ages are essential to constrain the past history of nearby galaxies, both in terms of their past metal contents and of SFHs. ...

. Astronomers discovered a new, complex quadruple-star system in Ophiuchus. The inset shows a subarcsecond spectroscopic binary discovered by Lowell Observatory astronomer Lisa Prato. This close binary, in turn, orbits a more widely spaced binary, so astronomers call the system a "hierarchical quadruple." . Lowell Observatory

The probability density function (PDF) is a simple analytical tool for determining the hierarchical spatial structure of molecular clouds. ... We have recently conducted a PDF analysis of the molecular gas in the G333 and Vela C giant molecular cloud complexes, using transitions of CO, HCN, HNC, HCO+ and N2H+. The results show that CO and its isotopologues trace mostly the log-normal part of the PDF, while HCN and HCO+ trace both a log-normal part and a power law part to the distribution. ...
