XANADU : Software dedicated to the analysis of X-ray images and spectra. The XANADU tasks are available at I.R.A. on the alpha axp workstations To work with XANADU tasks a personal username on Alpha WS is required To initialize the XANADU tasks you must enter the following commands (or put these in your .login file) ACTUAL Version: > setenv EXT osf > setenv XANADU /soft/astro/xanadu-new > source $XANADU/tools/initu.csh OLD Version: > setenv EXT osf > setenv XANADU /soft/astro/xanadu > source $XANADU/tools/initu.csh XSPEC is a command-driven, interactive, X-ray spectral fitting program. It is designed to be completely detector-independent so it can be used for any spectral instrument. Ginga, IUE, ROSAT PSPC, BBXRT, Astro-D, CCD e GIS) It has also been used for simulations of SAX, XTE, AXAF. The actual version is 9.00 The old version is 8.33 To work with XSPEC at the shell prompt type: xspec XRONOS is a general purpose timing analysis package. Although it was designed mostly for X-ray astronomy, XRONOS is basically detector and wavelenght-independed. It has been used to analyse data from the Einstein Observatory, EXOSAT and Ginga, as well as optical photometry and helioseismology data. It includes programs for: light curve(s), hardness radio and colour-colour plotting, epoch folding, power spectrum, autocorrelation, cross-correlation, time skewness and statistical analysis. The actual version is 3.01 To work with XRONOS at the shell prompt type: xronos XIMAGE is a multi-mission X-ray image display ans analysis program. It is designed to be instrument independent and to support the analysis of data from any X-ray imaging detector provided that the proper calibration files are available. Currently XIMAGE supports the detailed analysis of EXSOSAT CMA, Einstein HRI and IPC, ROSAT PSPC and HRI, and ASCA GIS and SIS data. It also support some basic analysis of optical, infrared and radio images. XIMAGE has built in data simulation program that can simulate images of current and future X-ray missions (e.g. SAX, AXAF and XMM). The actual version is 2.53 To work with XIMAGE at the shell prompt type: ximage QDP/PLT is the name of an interactive plotting and fitting FORTRAN subroutine. The QDP program accepts various commands at the top of the file followed by a two dimensional array of data. To work with QDP/PLT at the shell prompt type: qdp filename The XANADU packages User's Guide are available in three different forms: HTML pages (except for QDP/PLT) at the address: http://www.ira.inaf.it/ira-docs/calcolo.html Postscript files at the same web address Manuals at the room 307 Contact Person: F.Tinarelli tinarelli@ira.inaf.it
