301. ADASS 2003 Conference Proceedings
... Fekete, G., Szalay, A. S., & Gray, J. 2003, in ASP Conf. ... The hierarchical tringular mesh (HTM) is a discrete foundation for describing location, size and shape on the celestial sphere. Indices derived from HTM descriptors are used in a relational database for managing spatial information. ... We call these numbers HTM ID's, or hids for short. ... It provides an arbitrary resolution partitioning of the sphere, so that sets of hids encode a region. ...

303. ADASS 2003 Conference Proceedings
... This paper will describe very recent algorithms based on computational geometry which have dramatically reduced the computational complexity of 1) kernel density estimation (which also extends to nonparametric regression, classification, and clustering), and 2) the -point correlation function for arbitrary . ... Problems such as computing kernel density estimates and -point correlation functions correspond to summations over pairs, triples, or in general -tuples of points. ...

... This paper discuss the ISDC's experiences with our Data Access Layers (DAL). ... ISDC's DAL was designed to solve problems anticipated by the combination of Integral's 4 instruments, wide fields of view, many instrument modes, and new pointings approximantly every half hour. This would mean that any sensible scientific data analysis would process hundreds of individual files. ... CFITSIO is a fast efficient, easy to use library for reading and writing FITS files. ...

... Ortiz, P. 2003, in ASP Conf. ... Computer-assisted catalogue-merging utilities are the natural extension to manual methods used by astronomers to merge information from different catalogues in the pre-VO era. Recognizing which columns represent the same physical quantity is important not only to combine two or more tables, but it is of prime importance when the aim is to recognize sources with similar physical characteristics in an N-dimensional parameter space, ie, true data-mining. ...
