\secA{Example parameter files}
\label{app-input}

This is what a typical parameter file would look like.

\begin{verbatim}
imageFile       /home/mduchamp/fountain.fits
logFile         logfile.txt
outFile         results.txt
spectraFile     spectra.ps
flagSubsection  false
flagOutputRecon false
flagOutputResid 0
flagTrim        1
flagMW          1
minMW           75
maxMW           112
flagGrowth      1
growthCut       1.5
flagATrous      1
reconDim        1          
scaleMin        1
snrRecon        4
flagFDR         1
alphaFDR        0.1
snrCut          3
threshSpatial   3
threshVelocity  7
\end{verbatim}

Note that, as in this example, the flag parameters can be entered as
strings (\texttt{true}/\texttt{false}) or integers
(\texttt{1}/\texttt{0}). Also, note that it is not necessary to
include all these parameters in the file, only those that need to be
changed from the defaults (as listed in Appendix~\ref{app-param}),
which in this case would be very few. A minimal parameter file might
look like:
\begin{verbatim}
imageFile       /home/mduchamp/fountain.fits
flagLog         false
flagATrous      1
snrRecon        3
snrCut          2.5
minChannels     4
\end{verbatim}
This will reconstruct the cube with a lower SNR value than the
default, select objects at a lower threshold,  with a looser minimum
channel requirement, and not keep a log of the intermediate
detections. 

The following page demonstrates how the parameters are presented to
the user, both on the screen at execution time, and in the output and
log files. On each line, there is a description on the parameter, the
relevant parameter name that is used in the input file (if there is
one that the user can enter), and the value of the parameter being
used.
