Next: Modes of Operation Up: CCD Scientific Performance Previous: Field of View . Thermal excitation of charge carriers from the valence to the conduction band creates a dark current signal which may vary with position in the array, and also has temporal shot noise variation. ... In a device devoid of localized defects which give rise to individual dark current spikes , most dark current arises from electrons generated at interface states at the surface. ...

... A dynamo (or electric generator) is a device converting . ... Faraday discovered that by moving a magnet next to a closed electric circuit, or changing the magnetic field passing through it, an electric current could be "induced" to flow in it. ... Faraday's disk dynamo Faraday showed that another way of inducing the current was to move the electric conductor while the magnetic source stood still. ... Faraday's disk dynamo needs a magnetic field in order to produce an electric current. ...

... This page describes the format of the skin template files (.tmpl) that are used to create PmWiki skins . ... Each skin must include a template file that provides the skeleton for displaying a PmWiki page. A template file is basically an HTML file that also contains variable substitutions (indicated by '$') and special directives embedded in HTML comments. ... When PmWiki displays a page, it replaces the directives and variable substitutions with the values appropriate to the current page. ...

The threshold value is currently a slider/text field pair which have a precision of .0001. ... Like the Threshold value, the Flare Intensity has both a slider and a text input field for specifying its value. ...

... A data set contains a science frame, all its associated raw calibration frames and the master calibration frames created by combining and processing the raw calibration frames. ... Either one creates a MIDAS catalogue which contains the names of all single calibration frames to be combined in to the master frame, or, in the case of pipe line reduction, one use the Association Table. ... The names of single calibration frames are however also available in the Association Table. ...

Linux supports virtual memory , that is, using a disk as an extension of RAM so that the effective size of usable memory grows correspondingly. ... When the original contents are needed again, they are read back into memory. ... The part of the hard disk that is used as virtual memory is called the swap space . Linux can use either a normal file in the filesystem or a separate partition for swap space. ...
