FTOOLS Version 3.3 Summary:
===========================

The FTOOLS have now been ported to Silicon Graphics workstations running
IRIX.  With the release of Perl5, most FTOOLS Perl scripts can be run
on VMS machines (complete porting of all non-GUI scripts is planned).

New tasks available:

        abc - Apply Barycentric Corrections to ROSAT event data.
   ascaexpo - Generate an exposure map for an ASCA observation.
        bct - Produce a Barycenter Correction Table from ROSAT orbit data
        bkg - Subtract a background from a binned light curve
    col2img - Converts a collimator response dataset to an image
   fvec2img - Create an image from a column of vectors
  hriexpmap - Creates exposure map for given ROSAT HRI observational dataset
    hrifilt - Creates a ROSAT HRI makefilter file
    modalid - Print the space craft modal configuration
    perdgrm - Adds a sine curve and/or pulse-profile to a light curve.
     sky2xy - Transform from sky to pixel coordinates using WCS keywords
    src2pha - Creates a PHA file from specified extensions in an RDF src file
     xy2sky - Transform from pixel to sky coordinates using WCS keywords


XSELECT version 1.3 summary:
============================

New Commands:
* SISPI this will fill the PI column for SIS BRIGHT data.  This
  command is run automatically as a part of FAINT, so there is
  no reason to run it on FAINT data, but you can.

Bug Fixes:
* Sometimes Xselect would use the original data rather than the
  appropriate product events file.  This might cause the effects of
  SELECT EVENTS to get lost.  This is now fixed.
* The ROSAT support is more robust.

New Features:
* The default energy column for the ASCA SIS instruments is now PI


ROSAT FTOOLS News
============================

New tools:

 hrifilt   - Creates a ROSAT HRI makefilter file.
             The resultant makefilter file can be used to screen data
             using Xselect.

 hriexpmap - Creates exposure map for given ROSAT HRI observational dataset

 abc       - Apply Barycentric Corrections to ROSAT event data.

 bct       - Produce a Barycenter Correction Table from ROSAT orbit data.

 rosbary   - script to do ROSAT barycentric correction
             This runs abc and bct together.

 src2pha   - Creates a PHA file from specified extensions in an RDF
             src file. NOTE: There is a driver script to call this
             FTOOL, EXTPHA, type 'extpha' at your UNIX or DCL prompt
             and follow the directions.
 hiback    - Script to create a qsrc file from an src file.  It runs
             MKQSRC and adds a BKG_SUSP keyword to the output file as
             well.

HEASARC FTOOLS News
=============================

New features in GRPPHA:

Users are now  allowed to over-write the input  file. This can be achieved by
either setting the hidden  boolean parameter "clobber" to  yes, or by  making
use of the "!"-convention whereby the output filename is preceeded by an "!".

A new "family" of  command  strings, DUMP, has  been  introduced. DUMP allows
the user  to write an ascii file  containing the  current settings, this file
may be useful if the user wishes to apply the same settings in another GRPPHA
run. Currently there are 3 possible commands: DUMP GROUPING, DUMP SYSTEMATICS
and DUMP QUALITY.
