Fits Image Table

Image Table display

The table window presents a spreadsheet-like display of the
contents of the given FITS image extension.  Row numbers run along the
left side of the window and column numbers run along the top (below the
menubar).  Single click on a data cell to copy the value to the "Edit
cell" entry at the bottom of the window, where one can immediately edit the
value. Press <Return> in that entry to finalize the changes.

If the FITS image is simultaneously displayed in the POW image viewer, then 
double clicking with the mouse on any pixel in the POW image will cause
the corresponding cell in the table display to be highlighted.
