... efftplot (efftplot-2.11) [xmmsas_20041122_1834-6.1.0] . ... The parameters of powspec are computed from the parameters of efftplot , such that for each energy band, only one time-averaged PDS is computed. Then for each energy band, efftplot reads the PDS into the FITS file produced by powspec , and plots it with the PGPLOT library. ... 1 : PDS is normalized such that the (white) noise level expected corresponds to a power value of 2. ... 2 : as =2, but the expected white noise level is subtracted. ...

Returns a value from the normal distribution. virtual Double . ... These function allow you to manipulate the parameters (mean & variance) described above through the base class. virtual Vector < Double > . ... The second and third arguments define the parameters for this distribution as described in the synopsis. virtual casa::Normal::~Normal . ...

... SFIT is a general-purpose code designed to optimize theoretical stellar spectra to an observed spectrum. ... While the programme expects input from "stdio", it is more natural to save commands in a file (eg "sfit_input") and run the code simply by . ... If the spectra to be fitted have a filename "star_spectrum", then the best fit spectrum will be written out, together with the renormalized input spectrum, to a file called "star_spectrum.fit". ... sets up model spectrum grid (and for 2nd star) . ...

... This section describes three functions which have been created to cleanup defects in images. The first two functions for cleaning rows and columns are particularly useful for CCD--images. ... These can often be removed with the commands: MODIFY/COLUMN INPUT OUTPUT [C or V] [columns] . ... This is particularly useful for removing the permanent defects which may exist in the CCD--frames and which cannot be removed by the MODIFY/COLUMN or MODIFY/ROW commands. ...

This diagram illustrates a floating image that overlaps the borders of two paragraphs in normal flow: the paragraph borders are clipped by the non-transparent parts of the image. ... A left-floating image causes the final three lines of the upper paragraph to float along its right side. It causes the first three lines of the following paragraph to do the same, and the remainder of that paragraph flows normally. The paragraph borders shine through the margin area of the image box. ...

... A technique allowing automatic representation by a relatively small number of independent parameters based on the principal component analysis of data sequences is presented. ... In recent years the spectrum of observed astronomical data can be characterized as greatly varied. ... In this instance, the problem of initial description and classificati
