... Table data are arranged in columns and rows, and stored in MIDAS files with the extension .tbl . ... An item in a table is accessed by giving its column and row in addition to the table name. The row number can either be given as an absolute value (i.e. the sequence number) or indicated by the value in a previously defined reference column. ... A table can be always expanded in the sense that its number of columns and rows is automatically increased when the allocated space is exceeded. ...

... Previous: Access to Atomic and Molecular Data/Databases in the VO . ... We present the general characteristics of a database for binary and multiple stars from all observational categories, specifically designed to address the awkward topics of the identification of stellar components. BDB is based on a modular architecture to allow the easy integration of data from various sources. We describe in particular the set up of connections with other double star databases through the Internet. ...

... AstroAsciiData is a Python module to handle ASCII tables. ... The idea to develop this Python module emerged from the fact that ASCII tables continue to be one of the most popular and widely used data exchange formats in astronomy and probably science in general. ... To load this ASCII table, go into Python, load the AstroAsciiData module and read in the table with: . ... demo = asciidata.open('webexa.txt') . ... Users who only want to work with ASCII tables neeed no further python modules. ...

SAOtng supports display of photon event data contained in raw files, similar to its support for FITS Binary Table extensions (e.g., X-ray event lists). ... Because event files do not usually contain enough information to generate an image, we have adopted some conventions for specifying how to interpret the data in these files and for how to bin rows of events into images. To image an event file, it is first of all necessary to define the structure of the events in the event file. ...

Underdetermined sets is a new type of data structures (terms) developed in Actor Prolog . ... The point is that an underdetermined set can include some indefinite rest (a tail) like a list in usual Prolog . At the same time, the order of elements of an underdetermined set can be arbitrary one and it does not affect results of unification of underdetermined sets. Moreover, Actor Prolog guarantees that a rest of an underdetermined set never contains elements that are explicitly given in the set. ...
