... Microlocal Analysis is a theory of Pseudo-Differential Operators and Fourier Integral Operators (PDOs and FIOs). ... Microlocal analysis comes in few flavors. ... We will consider semi-classical PDOs and FIOs: one can always get from there to standard PDOs and FIOs but semi-classical theory has more applications. Less formal description of (semi-classical) microlocal analysis is ``a semi-classical limit of quantum mechanics'' or ``high-frequency limit of electrodynamics'' (etc). ...

Transformations which take functions, e.g. x , y as arguments and return functions as results are called operators. The direct and inverse Fourier transform, , and the convolution, , are operators defined in the following way: . where square brackets, , indicate the order of the operators and round brackets, , indicate the arguments of the input and output functions. ...

Next: CONCLUSION Up: CHIRPLET TRANSFORM SUBSPACES Previous: Nondilational Chirplet Transform . Suppose we choose a windowed sinusoidal FM signal for our mother chirplet. Such a signal has a frequency that periodically rises and falls (much like the vibrato of musical instruments or the wail of a police siren). ... Figure 14 . ... Using the warbling mother chirplet, we also computed the ``dilation-dilation'' ( ) plane of the chirplet transform (Fig. 16 ) for the pendulum data. ...

... A photometric analysis was made of the simulated images using two of the widely available reduction programs, ROMAFOT (Buonanno et al. 1983) and DAOPHOT (Stetson 1987). ... The rebinned and expanded image gave better results (Fig. 7b), with the smallest errors in the order of = 0.04. ... Similarly to ROMAFOT, the image with the Moffat PSF gave significantly better results than the image generated with the Tiny Tim PSF; the errors in the magnitudes of the brighter stars were around = 0.02. ...

... The task maths evaluates a mathematical expression at each pixel of a set of input images. The expression (given by the exp keyword) is given in a FORTRAN-like syntax, using all the normal FORTRAN operators, real-valued functions (using the FORTRAN generic, rather than specific, names), brackets and real constants. ... Dataset names take the place of FORTRAN variables, and the expression is each pixel of the input images. ... Expressions can potentially be constructed with no input datasets. ...

NOTE: Analyz routines for L-band receivers use OLD gain & noise diode values! Analyz is a data analysis program written at Arecibo back when you reduced (and took) Arecibo data on a Harris computer. ... So if you want a fairly simple program which can rapidly & efficiently reduce your spectral line data, then you may want to consider using Analyz. ...
