contpars: Set parameters for continuum removal
Package: rvsao
Usage
contpars
Parameters
- 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.
- c_sample "*"
- Sample of points to use in fit. "*" = all.
- c_function spline3
- Continuum fitting function (spline3 or legendre or chebyshev or spline1)
- 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.
- s_low_reject 2.
- Spectrum continuum fit minimum acceptance limit in sigma of fit
- s_high_reject 2.
- Spectrum continuum fit maximum acceptance limit in sigma of fit
- t_low_reject 2.
- Template continuum fit minimum acceptance limit in sigma of fit
- t_high_reject 2.
- Template continuum fit maximum acceptance limit in sigma of fit
- niterate 10
- Number of rejection iterations
- grow 1.
- Rejection growing radius
Description
contpars sets the parameters to be used to fit the continuum of spectra on which XCSAO or EMSAO are being run.
