Sub-packages

---

For convenience, the individual FTOOLS tasks are collected together in "sub-packages." Thus, the tasks that perform generic functions that could be appropriate for any type of FITS file (e.g., list the contents of a FITS file and write it to another FITS file), are distiguished from the mission-specific tasks that perform calibration or analysis functions on various kinds of high-energy astrophysics data.

General Subpackages

The following General subpackages are currently available:

Xselect

Xselect is a general driver which greatly simplifies many commonly performed tasks such as extracting images or spectra from events files. Xselect is distributed with the HEASARC package on the download page.

GUIs

Since v4.0, FTOOLS has had a new emphasis on graphical interfaces to the ftools. While the old command line functionality is still there for scripting or for those who just really like it, we encourage you to try the new interfaces; they may make your life a lot easier. The current GUI tools are:

• fv - A graphical FITS file editor for both tables and images.
• xdf - The XTE data finder. Allows easy traversal of an XTE data directory tree.
• xsut - XSUT is a tool designed by the RXTE GOF as a graphical front-end to the GNU tar program to help in selectively untarring RXTE (and RXTE only) data tapes or tar files
