1. IDEA: Methodological Principles
Next: Example of Deconvolution: Up: Interactive Deconvolution with Error Previous: Introduction . ... To a first approximation, the experimental data are related to the original object , the intensity of the source at some high level of resolution, by an experimental transfer relation: where is the Point Spread Function. ... The choice of its diameter is of fundamental importance because it is closely related to the resolution limit of the reconstruction process. ...

4. Housekeeping related keywords
... The task also issues a number of housekeeping related messages and values and also writes several keywords to the EXPOSURE extension (the information is usually CCD-dependent and it is thus important that it is kept and propagated through the event file processing chain). ... Filter: the filter wheel position is derived from the position sensor potentiometer (housekeeping column F1122 contained in the main periodic housekeeping file PNPMH1 , HK mnemonic H_CE_FWSPOT). ...

5. Frequency/duration relation.
... The concepts of Fourier frequency and wavelet duration are obviously related. ... Among many sensible definitions, we chose to require that the peak of the wavelet mean spectrum should be matched with the singularity of the Fourier transform of the cosine wave. Then, it can be shown that the frequency of the cosine is related to the wavelet duration by the relation . ... The ambiguous definition of the duration of an event is common to the sizing of any object of irregular shape. ...

Do LIRGs follow the Tully-Fisher relation? ... For a small we can say majority of investigate i Conclusion number of galaxies in our sample, that the T-F relation holds. ... The purpose of this research was to study the LIRGs (Luminous Infrared Galaxies) and see if they follow the Tully-Fisher relation. The LIRGs are different to normal galaxies in the fact that they emit 90% of their light in infrared. ... The faster the galaxy rotates, the wider is the emission line in velocity. ...
