The VLTI Calibrator Selector Tool is a tool intended to assist in the selection of suitable interferometric calibrators for VLTI observations with MIDI and AMBER. It uses a model of the VLTI and its instruments to assess the fringe visibility, given the observed bandpass, the geometry, spectrum, and coordinates of the target and the time at which the observations are to be made. ... The tool offers an HTML/Java based interface and consists of two pages. ... The quality flag depends on LDD_chi2. ...

... These plots show spectra (either count rates or ux) and the background count rates. omgrismplotplot can be used to display a single spectrum or multiple spectra, produced by omgrism. The input FITS les must contain net count rates, background count rates and the associated errors. The spectra must follow a regular binning scheme (i.e. equispaced wavelength bins). omgrismplot allows the user to input the device type (e.g. Xwindow, Postscript, ...) for output. ... 7 Output Files 1. ...

The A TNF S pectral A nalysis P ackage is a new software package that has been developed within the ATNF, to reduce single-dish, single-pointing spectral line observations. ASAP is now used for single-dish data from ATNF instruments and should be able to read data from any telescope if the data can be written in the "sdfits" format. ... The c++ code makes extensive used of the casa libraries (the package formerly known as aips++). ... A binary version for Fedora Linux should be available shortly. ...

Next: Model Spectra for Spectral-Fitting Up: Spectral Analysis Previous: A Quick Look at . ... For ROSAT PSPC data, this conversion is done during the on-line (SASS) processing. For IPC observations, the instrument gain varies both across the detector and in time, and is applied during off-line processing (PROS) using the BAL histogram. By default, spectra are extracted in PI bins for PSPC data and in PHA bins for IPC data. ... Special techniques are required when using Einstein IPC data. ...

... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). ... This was early evidence against the immutable nature of the heavens, although Brahe did not interpret the absence of parallax for stars correctly, as we discuss below. Brahe made careful observations of a comet in 1577. ...

The close position of main satellite and subsatellite (distance between them about 1000 km) and using the similar sets of Faraday cups (VDP and VDP-S) with high resolution measurements (up to 16 Hz for the main satellite and up to 10 Hz for the subsatellite) allow us to determine the small-scale variations of the magnetopause shape and position and to estimate the velocity of the magnetopause motion. ...
