Xselect is a command line interface to the Ftools, for X-ray astrophysical analysis. It has four major functions:
Xselect also contains routines of importance for specific missions. Currently, there are only ASCA specific commands, namely sisclean, gisclean, faint and fast. Xselect can be set up to support any new mission or instrument that does not require mission-specific routines simply by editing the mission database file (xselect.mdb). The mission database file distributed with xselect v2.4 contains complete support for ASCA, BBXRT, EINSTEIN (IPC and HRI), EXOSAT, ROSAT, BeppoSAX (LECS, MECS, and PDS), Swift (XRT and UVOT), XTE PCA standard2, Chandra (ACIS and HRC), XMM-Newton (EPIC) and initial support for ASTRO-E2 and SPECTRUM-RG (JET-X).
In addition, there are routines to plot up various aspects of the event data, and of the HK and auxiliary filter data.
There are also general utility commands to view the internal state of Xselect, to view the raw data files, to clear various selections, data choices, etc., and to save the products of the analysis.
After v2.0 xselect comes in three flavors. The old interface is available by running the command xselect as before however for the adventurous we are also supplying xseltcl, running Tcl as its user interface, and ixselect, a graphical user interface to xseltcl. Both these new variants run exactly the same commands as the standard version except that the commands list, load, read, and set are renamed to xlist, xload, xread, and xset to avoid conflicts with native Tcl commands.
This users' guide has two main sections. The overview provides a brief tutorial on the use of Xselect while the commands section describes the individual commands in more detail. The appendices describe how to add new missions to Xselect, how the command line parser works, any features/bugs, and the names of the temporary files created by Xselect.
A note on the usage of this manual before we proceed: each Xselect session is given a session prefix, which is prepended to the names of the product files, and appears in the prompts. In the rest of this manual, we will use the default session name: xsel. Replace this with your own session name for all the Xselect temporary files.
