New features/Bug fixes since V4.1.3 include:
- Correct background backup directory cleanup process.
- Add capability to plot to existing graph in DS9.
Version 4.1.3 July 2004
New features/Bug fixes since V4.1.2 include:
- Update calculator, calculator expression help files.
- Add licence.
- Fix interface to VizieR.
- Add A4 paper size.
- Rework print interfac.
- Fix preview orientation.
- Fix preview page layout.

Version 4.1.2 May 2004
New features since V4.1.1 include:
- Adding support for Cartesian projection.
- Adding record capability for profile of FITS image.
- Enhanced capabilities for printing and saving FITS image or plot, including the
ability to preview the image before printing.
- A row selection function was added to fv. User can select/deselect row(s) by
clicking on the row index in the table with the mouse's left button (or
clicking left button then right button to select row range). Row(s) also can
be selected using selection condition and expression.
- fv's plot, calculator, histogram and statistics tools now can perform on the
selected rows.
- Export command can export the selected rows and columns from a table to
fits file or text file.
- Delete command will now delete the selected rows and cols.
Version 4.1.1 January 2004
New features since V3.2 include:
- Enhanced support for ds9 image display
User can choose to display images or plots using either
DS9 or POW as the primary display tool.
- Added more XPA points for controlling fv from external processes, including
create: create an image or table file or extension.
export: export hdu(s) to a Fits file or a text file.
opentool: open skyview, catalog, vizier, or ftools dialog panel.
preference: set up FV preferences.
See Scripting for more information
- Allow user to reverse the functionality of the left and right mouse
buttons within the POW display via pow's preferences setting
default: Left mouse button - control zoom
right mouse button - control brightness/contrast
Version 3.2 October 2002

user-specified character string between each columns value
- Double Right-clicking inside a pow graph redraws the graph with
