Next: Computation Up: Image Deconvolution Previous: Computation . ... The Maximum Entropy Method (MEM) is not procedural. ... Typically this is a flux constraint, which ensures that the flux density in the maximum entropy image is correct. That is, the flux density of the maximum entropy image, . ... This is quite a useful constraint. Although the maximum entropy task, described below, does not force you to give a flux constraint, you should attempt to, if at all possible. ... Computation . ...

Also, the Heliocentric correction cannot be applied to such lightcurves. ... This period search service is also available at the mirror sites: Mirror 1 , Mirror 2 , Mirror 3 , Mirror 4 . You may download the latest source code distribution and install the period search service at your own web server. ...

XMM-Newton Science Analysis System . ... A different approach is done via the setting withctisrcpos =Y: all event energy corrections do not use the actual RAWY coordinate but the corresponding RAWY location of the source ( SRCPOS ) as determined by the task epframes (either automatically or via setting withsrccoords =Y). ... The task epchain may be used with the setting ccds =4 withctisrcpos =Y to process only the CCD 4 where usually the bright source is located that causes the Out-of-Time events. ...

... Recognition of Anomalous Events S. Monai 1,2 and F.Pasian 2 1 Osservatorio Astronomico di Brera Merate, Italy 2 Osservatorio Astronomico di Trieste, Italy Abstract. We present an original algorithm for the recognition of anomalous events in a CCD frame (i.e., cosmic hits, bad pixels etc.) ... Raw images, as read from a CCD, are often a#ected by some events which are revealed by anomalous pixel values, i.e., single saturated pixels or pixels at zero intensity (also named hot or bad pixels). ...

... Take a particularly simple signal: a cosine wave. ... Now, we are going to stretch and shrink the wavelet along the time axis (we assume the data is in the time domain), and at each time compare the shape of the signal to that of the wavelet. ... Figure 3: The wavelet (dotted line) is translated rela tive to the signal (solid line). ... Figure 4: The dashed line plots the `match' between the wavelets (dotted line) and the signal (solid line) as a function of time. ...

... The distinction of our approach is in that we unite the Actor Prolog concurrent ob ject-oriented logic language [ 1,2,3] with the Structural Analysis and Design Technique (SADT) diagrams to obtain new issues in the following areas: 1. ... Graphic user interface management. ... The individual blocks of visual user interface based on the SADT diagrams are implemented by using parallel processes of Actor Prolog. ...
