NAME
contpars -- Parameter set for continuum and line removal
.ih
USAGE
contpars
.ih
PARAMETERS
.ls c_interactive no
Fit continuum interactively (yes or no).  If yes, a graph of the spectrum
and the continuum fit is plotted to stdgraph, with rejected points flagged.
"q" accepts the fit and continues the main task, "?" prints options,
"d" deletes points, "u" undeletes points, "f" refits and redraws the data.
.le
.ls c_sample "*"
Sample of points to use in fit. "*" = all.
.le
.ls c_function spline3
Continuum fitting function (spline3 or legendre or chebyshev or spline1)
.le
.ls naverage 1
Number of points in sample averaging
.le
.ls order 1
Order of fitting function.  This is the IRAF order, i.e. the number of
coefficients, not what you might expect.  If order=0, no continuum is
fit or removed.
.le
.ls s_low_reject 2.
Spectrum continuum fit minimum acceptance limit in sigma of fit
.le
.ls s_high_reject 2.
Spectrum continuum fit maximum acceptance limit in sigma of fit
.le
.ls t_low_reject 2.
Template continuum fit minimum acceptance limit in sigma of fit
.le
.ls t_high_reject 2.
Template continuum fit maximum acceptance limit in sigma of fit
.le
.ls niterate 10
Number of rejection iterations
.le
.ls grow 1.
Rejection growing radius
.le

DESCRIPTION

\fIcontpars\fR sets the parameters to be used to fit the continuum of
spectra on which XCSAO or EMSAO are being run.
