... A Multidimensional Binary Search Tree for Star Catalog Correlations D. Nguyen, K. DuPrie and P. Zografou Smithsonian Astrophysical Observatory, Cambridge, MA 02138 Abstract. A multi­dimensional binary search tree, k­d tree, is proposed to support range queries in multi­key data sets. ... Data Volume Limitation If the k number of keys to be searched for contain RA, Dec and some other attributes then one can minimize the number of nodes in the tree by utilizing only the near neighbor FITS files. ...

... The numbers of three types of compact binaries containing accreting NSs and BHs, which are most interesting from the point of view of their observational appearances, have been calculated as a function of time: i) X-ray transient source containing a NS in an eccentric orbit around a main sequence Be-star (the observed prototype: A0535+26), ii) BH The evolution of the selected types of X-ray binaries during the first 10 million years after the starburst onset is presented in Fig. ...

This directory contains prototypes for scripts that may be called by the camera driver. ... The script set_camera_filter should take a filter number as an argument and send a command to a filter wheel. The SBIG filter wheel is supported internally and does not use this script. If you have another filter wheel, then a script such as this would allow you to use XmCCD to control the filter wheel. ... Simply "make" the routine in the ifw directory, and then "make install". ...
