            option
            of 'Default',
            which will not set any font options, if selected. This
            allows the

            and
            graphs,
            with no regions.</tt></li>
        <li> <tt>10.21.2002 Fixed a problem with old prefs files and
            marker(system).</tt></li>
        <li> <tt>10.22.2002 Fixed a problem with MINMAX Sample. Sample
            intervals are

        <li> <tt>08.05.2002 fixed a problem for the windows port where
            windows
            has been
            configured to open a fits file with ds9. In this case, the
            file path
            name
            passed to ds9 is actually in 'dos' format. So we used a
            cygwin function
            to convert to a posix format. This only occurs in a command
            line file
            name
            option.</tt></li>
        <li> <tt>08.06.2002 fixed a problem with smooth and depth&gt;1.</tt></li>

        <li> <tt>04.05.2002 improved parsing of analysis menu file. In
            particular, keywords
            like 'help', 'param', and 'end' can be used more freely.</tt></li>
        <li> <tt>04.10.2002 add tag suppport for regions.</tt></li>
        <li> <tt>04.11.2002 add background marker stack. The default

            is

        <li> <tt>04.11.2002 fixed checks for can Edit, can Move, can

        <li> <tt>04.12.2002 add $null macro to analysis support.</tt></li>
        <li> <tt>04.17.2002 fitsy++ now builds an keyword index to
            search
            for
            keywords.
            Previously, it would search sequentially.</tt></li>
        <li> <tt>04.18.2002 add a fix to ps level 2 driver to prevent a
            '\n%'
            in the
            image data. Seems the perl script 'assemble' does a global
            search/replace
            that results in corrupted image data. This fix includes a
            redesign of a
            previous fix that worked around an issue with old versions
            of dvips
            that
            will incorrectly process'\n%%'.</tt></li>
        <li> <tt>04.18.2002 upgrade to WCS 3.1.0</tt></li>
        <li> <tt>04.24.2002 start to add support for multiple wcs's.</tt></li>
        <li> <tt>04.25.2002 add support for multiple wcs's in infobox.</tt></li>
        <li> <tt>04.26.2002 improve tag support for regions. All
            functionality
            of selected
            regions are now available for tagged regions.</tt></li>
        <li> <tt>04.30.2002 add marker command var command to support
            regions
            files
            in tcl vars.</tt></li>
        <li> <tt>05.08.2002 recalc polygon center when adding or
            deleteing
            vertex.</tt></li>
        <li> <tt>05.13.2002 complete implementation of multiple wcs
            support.
            ds9 now
            supports a total of 31 coordinate systems. Furthermore, of
            the 27 WCS
            coordinate
            systems, both sky coordinates and linear coordinates are
            fully
            supported.</tt></li>
        <li> <tt>05.13.2002 complete re-implemenation of map()
            functions.
            Now
            all map
            functions are in the fits case, and only map between REF and
            IMAGE/PHYSICAL/AMPLIFIER/DETECTOR/WCS/WCSA...
            coordinate systems. This cleans up alot of code and
            confusion.</tt></li>
        <li> <tt>05.14.2002 add support for TCROT and CDn_1 WCS
            keywords
            in
            FITS bin
            tables.</tt></li>
        <li> <tt>05.16.2002 dramatically speed up parsing wcs keywords
            by
            substituting
            the fitsy++ index based keyword search routine for Doug
            Mink's
            'ksearch'
            routine. With multiple wcs's in a large mosaic this can save
            up to a
            minute
            at load time.</tt></li>
        <li> <tt>05.16.2002 fixed a minor problem with xpa dss. http
            has a
            error, that
            carries over and is caught by xpa.</tt></li>
        <li> <tt>05.16.2002 analysis $text windows will not appear if
            there is
            no output,
            or just an &lt;cr&gt;.</tt></li>
        <li> <tt>05.16.2002 fixed display header to correctly display
            80
            chars, not
            79.</tt></li>
        <li> <tt>05.16.2002 fixed a problem with iis and very long file
            names.
            names
            up to 256 chars are now allowed.</tt></li>
        <li> <tt>005.20.2002 AMPLIFER and DETECTOR coordinate menu
            entries
            are
            now an
            option, to be enabled via the Preferences:Misc menu option.
            Changes
            will
            take affect at startup.</tt></li>

            tables.</tt></li>
        <li> <tt>05.24.2002 made changes to grid.C to handle the
            special
            LONG/NPOL skyframe
            coordinate system used by Chandra.</tt></li>
        <li> <tt>05.24.2002 add -xpa and xpa prefs to allow a user to
            enable
            or disable
            initialization of XPA at startup</tt></li>
        <li> <tt>05.28.2002 add -xpa [inet|local|unix|localhost] xpa
            point.</tt></li>
        <li> <tt>05.29.2002 correct 3D binning to properly reflect
            filter
            params in
            the filename.</tt></li>
        <li> <tt>06.03.2002 fixed a problem with Fits Bin Tables, odd

        <li> <tt>06.04.2002 add -xpa noxpans support.</tt></li>
        <li> <tt>06.04.2002 match frames wcs now uses the wcs system
            and
            wcs
            skyframe
            specified in align to wcs.</tt></li>
        <li> <tt>06.05.2002 upgrade to xpa 2.1.1</tt></li>
        <li> <tt>06.06.2002 add wcs master menu and buttons</tt></li>
        <li> <tt>06.06.2002 sync xpa wcs and command line wcs command.</tt></li>
        <li> <tt>06.10.2002 xpa wcs and commanline -wcs now uses same
            code
            to
            process</tt></li>
        <li> <tt>06.10.2002 xpa nameserver format now skyformat</tt></li>
        <li> <tt>06.10.2002 added support for variable args for xpa
            contour
            and -contour.</tt></li>
        <li> <tt>06.11.2002 add match frames physical, amplifier,
            detector.
            this does
            not handle rotation, nor orientation.</tt></li>
        <li> <tt>06.11.2002 the master wcs menu now modifies the
            Region:File
            Coordinate
            System menu also</tt></li>
        <li> <tt>06.11.2002 fixed a problem with list projection and
            linear
            wcs. the
            thickness parameter was not written correctly.</tt></li>
        <li> <tt>06.12.2002 fixed a problem with -tile and -region
            commandline
            options.
            The ds9 window must be realized before processing region
            files.</tt></li>
        <li> <tt>06.13.2002 fixed a problem with -pagesetup commandline
            option.</tt></li>
        <li> <tt>06.13.2002 fixed a problem with ds9parser.Y,
            prosparser.Y,
            and tngparser.Y
            when processing coordinates when no coordinate system has
            been
            specified.</tt></li>
        <li> <tt>06.13.2002 fixed a problem with -pan to command line
            option.
            The ds9
            window needs to be realized (and the matrices defined)
            before
            processing.</tt></li>
        <li> <tt>06.13.2002 binning on a third column now invokes the
            data
            cube dialog
            box.</tt></li>
        <li> <tt>06.14.2002 add smaller buffer sizes to binning menus.
            We
            want
            to do
            this for those building large 3D binning movies.</tt></li>
        <li> <tt>06.19.2002 implemented new grid support. Grids now
            handle

            much better. Numerics are better positioned.</tt></li>
        <li> <tt>06.27.2002 updated to WCSSUBS 3.1.1. This corrects a

        <li> <tt>07.23.2002 add async support for internal web browser.</tt></li>
        <li> <tt>07.24.2002 changed Makefiles so that parser.C,
            parser.C.h,
            and lex.C
            are now archived. Therefor, builds no longer need bison and
            flex,
            unless
            changes have been made to the parser.Y. This gets around
            problems with
            different versions of bison.</tt></li>
        <li> <tt>07.25.2002 add support for the Compass region.</tt></li>
