As a result, a common magnitude scale (contour lines on the maps above, or color scale on Fig.1) will poorly display the short-duration events in a signal. Normalizing each line of the map (fixed duration) so it has unit variance (in effect dividing the energy map by the mean energy spectrum) at each duration restores more details of small-scale activity (Fig. ...

... Return to the Kernel page . ... This article is part of the LWN Porting Drivers to 2.6 series . The 2.6 kernel makes extensive use of per-CPU data - arrays containing one object for each processor on the system. Per-CPU variables are not suitable for every task, but, in situations where they can be used, they do offer a couple of advantages: . Per-CPU variables have fewer locking requirements since they are (normally) only accessed by a single processor. ... DEFINE_PER_CPU(type, name); . ...

. Next: Unix Interaction Up: Interactive environment Previous: Leading Spaces Index . During normal data processing, the user will have to create named variables to hold spectra etc. These must conform to the normal python syntax, specifically they cannot contain ``special'' characters such as $ etc and cannot start with a number (but can contain numbers). Variable (and function) names are case sensitive. Malte Marquarding 2007-08-16

... A frequently used procedure, alternative to the correction for the chromatic response, is to normalise the continuum to unity by dividing the observed spectrum by a smooth approximation of its continuum. This approximation can be obtained either interactively with the graphic cursor, or from a table (command NORMALIZE/SPECTRUM ) or by dividing the raw data by itself after filtering or smoothing. Median filtering and running average algorithms are well suited for this purpose (command FILTER ). ...

... In , the visibility amplitudes and phases of the program stars are calibrated using calibrator stars, for which those variables are modeled and the resulting model coefficients transferred to the program star data. ... When calibrating the data, the user should begin by looking at the calibrated and normalized amplitudes first to see whether the data has already been calibrated (for example when a .cha file was read). ... In the case of visibility phases, there are no normalized quantities.) ...
