Funtools Overview

echo "Funtools Tasks in DS9\r\rThe tasks in this section of the Analysis menu utilize the Funtools programs\r'funcnts' and 'funhist'. With the exceptions noted below, they all work off the \roriginal disk-based FITS file. The funcnts-based tasks (radial profile, counts\rin regions) present their results using WCS units, if the appropriate info is\rpresent in the FITS header. \r\rFor situations where a disk file is not available (e.g., image data generated\rby a program and sent to DS9's 'fits' XPA access point), alternate versions of\rthe radial profile and counts in regions tasks are offered that work from DS9's\rinternal image data. In these two cases, results are presented in pixels. Aside\rfrom the units, the results should be identical to the file-based results.\r\rFor more sophisticated analysis, please consider using the underlying Funtools\rtasks directly. These are documented at:\r\r http://hea-www.harvard.edu/RD/funtools/programs.html\r\r" | $text
