... For spectra a transformation from wavelength to frequency is used to identify spectral regions which follow a power law. This transformation is given by . ... Whereas the transforms mentioned above only perform a non--linear rebinning of the data, the Fourier transform converts a spatial image into the frequency domain. ... As an example of using Fourier transforms to extract information from a frame, an azimuthal intensity profile of the spiral galaxy A0526--16 is shown in Figure . ...

T he Siding Spring Survey (SSS) is a Near-Earth Object search program that utilises the 0.5-m Uppsala Schmidt Telescope at Siding Spring Observatory, N.S.W., Australia. ... The mission of the Siding Spring Survey is to contribute to the inventory of near-earth objects (NEOs), or more specifically, the potentially hazardous asteroids (PHAs) and comets (PHOs) that may pose a threat of impact and thus harm to civilization. ... Based on the CSS Mission page . ... Siding Spring Survey Main Page . ...

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. ...

grdfft - Perform mathematical operations on grdfiles in the frequency domain grdfft in _ grdfile -G out _ grdfile [ -A azimuth ] [ -C zlevel ] [ -D [ scale |g ] ] [ -E [ x|y ][ w ] ] [ -F [ x | ... The horizontal dimensions of the grdfiles are assumed to be in meters. ... Append a scale to multiply by (kr * scale ) instead. Alternatively, append g to indicate that your data are geoid heights in meters and output should be gravity anomalies in mGal. Default is no scale]. ...

Program: TRANSFORM Purpose: Transform a (sub)set using rotation, scaling, translation etc. ... This set will be transformed to OUTSET=, using a concatenation of simple operations like rotation, scaling, translation etc. ... POS= Enter position of centre: [0,0] All operations are defined with respect to a central point. ... If, for example, you want to rotate an object about its centre, then determine the position of this centre (e.g. -6.2 8.5) and enter these numbers here (e.g. POS= -6.2 8.5). ...

... The Time shift for April, 17-18 20 April 1999 . ... The INTMINS April 1999 operations schedule was done on the base of the MIR ground track long-term prediction using the MIR's orbital elements status on 29/03/99 . ... The investigation of the time shift behaviour was began before 29/03/99 on the base of the different orbital elements determined (by KIAM RAN) 22/03/99, 25/03/99 and continued on the base of the orbital elements determined at 31/03/99, 5/04/99. ... Modified 20 April 1999  ...

Next: NOVIDAS and UVPROC II-Data Archive and Reduction System for Nobeyama Millimeter Array . ... The RATAN-600 radio telescope allows us to carry out simultaneous multi-frequency observations using wide-band radiometers. ... Using these features a flexible astronomical data processing system (FADPS), operating on different UNIX platforms, was created. ... FADPS commands may be executed directly in UNIX, in scripts, or using a special shell for our data processing system in the X-Window system. ...

The Cosmic Background Imager T. J. Pearson et al. California Institute of Technology The Cosmic Background Imager (CBI) is an instrument designed to make images of the cosmic microwave background radiation and to measure its statistical properties on angular scales from 5 arc minutes to one degree (spherical harmonic scales from l  3000 down to l  300). The CBI is a 13-element interferometer mounted on a 6 meter platform operating in ten 1-GHz frequency bands from 26 GHz to 36 GHz. ...
