... Both selfcal and gpscal assume that the gains are independent of frequency. ... If all the visibilities for a given baseline go through one signal path, then the instrumental phase for the different visibilities should be equal (assuming the signal path is well equalised). ... If the visibilities for a given baseline go through multiple signal paths ( e.g. the 2 IF system for the ATCA), then the instrumental phases for the different paths could be significantly different. ...

... specadd creates a multiple X-ray spectrum FITS file by stacking or putting together (``adding'') two single spectrum files. ... This type of spectral files is particularly useful when the user wants to simultaneously analyse different observations of the same object carried out with the same instrument or with different instruments. ... The Data extension for a multiple spectral dataset stores one single spectrum per row, instead of one channel per row as it is the case of single spectrum files. ...

... Apache HTTP Server Version 2.2 . ... This document describes the use of Apache's Handlers. ... A "handler" is an internal Apache representation of the action to be performed when a file is called. Generally, files have implicit handlers, based on the file type. Normally, all files are simply served by the server, but certain file types are "handled" separately. ... The following directives will enable the send-as-is handler, which is used for files which contain their own HTTP headers. ...

OptInt PmWiki : Pm Wiki / Simultaneous Edits . ... Alice starts to edit a page. ... Alice finishes editing her page, hits "save", and since she was working from a version of the page from before Bob had made his changes, she wipes out Bob's edits in the process. PmWiki's simultaneous edit feature detects when this occurs, and instead of saving Alice's edits PmWiki presents Alice with a message that someone else changed the page while she was editing it. ...

... Thomson's multiple window method of spectral estimationthomson provides a very good estimate of the power spectrum by measuring the energy contained within a collection of rectangular shaped frequency intervals. ... Often, much of the fine structure of a spectral estimate is due to noise. It should be stressed that while other methods of spectral estimation (such as the Welchoppenheim method) exist, the Thomson method is particularly noteworthy for its precisely defined rectangular frequency bins. ...

This set of lessons teaches you how to manipulate data, plot it, analyse it and draw conclusions from it. Two software packages are used: Excel (or another spreadsheet such as iWork Numbers), and Python (with the numerical python and matplotlib packages). Some tasks can be done in either, while some require the greater power of Python. Reference Guide for Python Data Handling . Back to Main Lab Skills Page .

... Some of them are demonstrated above, and I'll address the "how-to" aspects one by one. ... Save your image as transparent based on the average color of your background tile. ... It will appear to be all one color now, but it's still finely dithered. Use your eyedropper tool to select one of the colors, and fill the bottom layer of your working image with it. ... Either way you go, this method is the first step to for all the other ones, it's from this file that we get our transparency mask. ...

The command list is placed between single quotes, as the command line is scanned twice, once when the shell first encounters the trap command and again when it is being executed. trap ' command-list ' signal-list . ... If command-list is not specified, then the action taken on receipt of any signal in the signal-list is reset to the default system action. If command-list is an explicitly quoted null command (' ' or " "), then the signals in signal-list are ignored by the shell. ...

... These are just the bare bones--just three basic ideas and rules for handling relations ("equations") involving unknown quantities whose values you are trying to find. In most calculations you try to find a number . ... To get a solution, one must replace the given equation (or equations) with others, containing the same information but cleaner in appearance. ... If you have an equation and modify both its sides in exactly the same way, what you get is also a valid equation. ...
