XMM-Newton Science Analysis System Page: 1 gtialign March 18, 2004 Abstract Align asynchronous GTI les to frame readout boundaries 1 Instruments/Modes Instrument Mode EPIC All RGS All OM Fast Note that the primary use of this task is foreseen to be with the EPIC imaging mode and with the RGS. ... The output GTI's are also useful for timing analysis. ... There should be exposure extension(s) in the event list, which will contain the frame readout times for the events in this le. ...

... As described in "Tabular Storage of STIS Data" on page 20-5 , raw time-tagged Sdata are stored in an event table which contains separate columns for the x and y pixel coordinates and the arrival time of each detected photon event. ... Generate a series of ACCUMulated images from user specified time intervals of data and then process the image(s) with calstis . ... The default behavior for inttag is to accumulate all events from the table, writing the results as one image set in the output FITS file....

Next: Photometry Up: Regions and Source Parameters Previous: *imcnts* - Find counts . This task (developed for use with optical images, but also useful with x-ray data) will quickly compute location, size, ellipticity, and position angle of sources. ... User can generate contour plots of any portion of the image and count rates in slices through the image. The program is advertised as ``quick [optical] photometry''. input file: rp110590_im1.imh . output file: logfile . ... Photometry . ...

The FITS archive & data processing pipelines . ... The archived data are broad band images (BBI) and long-slit spectra (LSS) plus their associated template and calibration files. The data in HFA can enter into the HyperLeda processing pipeline and the results can be freely downloaded. ... Definition of the file system (structure of the archive) . ... The coordinate systems must be updated when the data (pixel data, other keywords, related tables) are altered (eg. rebinning of the image). ...

The Network Time Protocol (NTP) is used to synchronize the time of a computer client or server to another server or reference time source, such as a radio or satellite receiver or modem. ... Information on the NTP architecture, protocol and algorithms can be found in the following articles and reports, which are available online . Mills, D.L. Internet time synchronization: the Network Time Protocol. ... Mills, D.L. Network Time Protocol (Version 3) specification, implementation and analysis. ...

... The system is general, due to some simple naming conventions for database tables. ... Furthermore, the interface allows X-Y plotting of any two numerical quantities retrieved from the database, and access to data archives distributed over Internet, following the WWW concept. ... The user interface allows access to the underlying structure of the archive: a catalogue managed by a commercial SQL-based database management system, and a data bank holding the original data and compressed quick-look data....

Each Apache configuration directive is described using a common format that looks like this: . ... This indicates the format of the directive as it would appear in a configuration file. This syntax is extremely directive-specific, and is described in detail in the directive's definition. ... If the directive has a default value ( i.e. , if you omit it from your configuration entirely, the Apache Web server will behave as though you set it to a particular value), it is described here. ...

... Directives | ... Apache HTTP Server Version 2.4 . ... This document describes the terms that are used to describe each Apache configuration directive . ... Configuration files . ... This indicates where in the server's configuration files the directive is legal. ... A directive marked as being valid in this context may be used inside <Directory> , <Location> , <Files> , and <Proxy> containers in the server configuration files, subject to the restrictions outlined in Configuration Sections .htaccess ...

... There are compelling reasons for the pulsar community to utilise a standard data storage format. For example, standardisation of file formats significantly decreases the amount of effort required to integrate new instruments into the analysis chain. ... Accordingly, we have defined PSRFITS as a standard FITS-based format for pulsar data files. ... For example, the first line of Processing History HDU contains information about the data acquisition program and the initial structure of the file. ...
