... Some existing (e.g., USNO-A1.0) and most of the upcoming catalogs (e.g., GSC-II SDSS , GAIA ) contain data for half a billion up to several billion objects. ... Here we present methods for structuring and searching very large catalogs to provide fast access to the coordinate domain of the parameter space. ... By generalising such methods it is also possible to produce catalog structures and indexes for accessing a multi dimensional parameter space. ...

Databases (NSDC) of the Natural Planetary Satellites. ... NSDC: Database of astrometric observations of Natural Planetary Satellites . ... They are thoroughly looking for observations in different sources, creating their owndatabases which are then mostly inaccessible to other researchers. ... In the file "content" with explications, the reference is given to the data source as well as the bibliographic reference. ... Data sources. ... Why a specific bibliographic database for Natural satellites? ...

XMM-Newton Science Analysis System Page: 1 calview July 2, 2008 Abstract An interactive viewer of the XMM calibration database. 1 Instruments/Modes Instrument Mode all all 2 Use pipeline processing no interactive analysis yes 3 Description The XMM calibration database is comprised of  100 calibration datasets (the current calibration le, or CCF [1]), and a number of calibration algorithms and access functions (the calibration access layer, or cal). ... The former is described in detail in cal. ...

... He considers some practical aspects of dependences of the optical properties of cosmic dust analogs on their parameters. ... First results of a systemtic study as well as a detailed comparison of different optical characteristics (cross-sections, phase function, etc.) of some complex shape and structure scatterers and their optical models are presented here and here . ...

... overview of pyQC . ... output used by . ... All pyQC scripts and modules share a similar structure. Python offers to group functions, classes, etc. into modules which can be imported by different scripts. ... In order to avoid confusion if names are used by different (especially external) modules, the QC scripts use the 'from' statement only for pyQC modules, i.e.: . ... For other modules, the simple 'import' statement is used: . ... Python modules are also used for keeping script configuration. ...

Russian SHAREABLE DATA CENTER Institute of Solar-Terrestial Physics SB RAS . ... Although their determination is based on the scattering process model, independent check-ups by rocket experiments have shown their correctness in experimental applications. ... Ionospheric data analysis, especially during strong disturbances, cannot be without some other kinds of diagnostic tools. ... The lack of data has always been a challange in this case. ...

Smareglia Osservatorio Astronomico di Trieste, 34131 Trieste, Italy Email: pasian@ts.astro.it Abstract. ... The basic user query would simply be the submission of an input image, either 1­D or 2­D; the system should allow retrieval of archived images similar to an input one on the basis of some ``resemblance parameter''. ... the QUBE User Interface. ...

... Reference Files . ... Reference files used by the ACS calibration pipeline (CALACS and PyDrizzle/MultiDrizzle) are updated on a regular basis. ... If you would like to receive an e-mail every time a new ACS reference file is delivered and the database is updated, you can subscribe to the acs_reffiles_upd mailing list. ... The pixels affected by these reference files are generally identified by data quality flags in the [DQ] extension of calibrated FITS data. ... ACS Distortion Correction Tables . ...

... Several of the tasks in the spectral package share a common set of parameters. ... Each task in the spectral package has a hidden parameter which points to the pkgpars parameter file. The parameters stored here include the observed data sets and the model descriptor, and instrument-specific parameters. ... The observed counts and error data set contained in the table file ( *_obs.tab ) produced by qpspec will be the input data for subsequent spectral tasks. ...
