1. Power Spectral Analysis
Next: Results Up: High Resolution Measurements from Previous: Introduction . The first step in PSA is to Fourier transform the image and calculate the square modulus of the FT to generate the power spectrum, . ... Specifically, one excludes the very lowest frequencies where the large scale nonuniformities in the image have the greatest effect, and one limits the fit to a frequency range where the SNR is sufficiently high. ...

5. ASpect: A Multi-Wavelength Spectrum Analysis Package for IRAF
... ASpect is spectrum analysis package being developed at ST ScI. We discuss the implementation of a GUI using the IRAF Object Manager, the ASpect task design, and the mechanics of performing a fit to a spectral feature with ASpect. ASpect is a spectrum and line analysis package being developed at ST ScI. ... For example, the fit library ``knows'' about the component and spectrum objects but a given spectrum or component object knows nothing of fitting. ...

10. Simulating Atmospheric Phase Errors, Phase Correction and the Impact on ALMA
... ALMA . ... OOF software . ... Software . ... We present a framework for modelling atmospheric phase errors and their correction by both the fast-switching and water vapour radiometeric techniques. Notable features are simulating three dimensional turbulent volumes instead of flat phase screens, considering three representative configurations of ALMA and parametrisation in terms of phase fluctuations on a 300m baseline, allowing referencing to the site-testing interferometer data. ...

... Initial mass function and binary stars . ... The principal goal of this study is to show that the real shape of the initial mass function for low- and intermediate-mass stars differs from the observed one. In particular, comparison of radii of eclipsing binary components and single stars shows a noticeable difference for B0V-G0V components of eclipsing binaries and single stars of the corresponding spectral type. ...
