prepare.IndoUS: Read an Indo-US Spectrum as Template

In oczoske/slacR: R-package to measure v and sigma from VIMOS IFU cubes

Description

This function provides a wrapper to prepare.template specifically geared to Indo-US spectra.

Usage

prepare.IndoUS(ident, config.file = NULL, path = NULL,
               lambda.lim = NULL, resolution.target, ...)

Arguments

ident	character string identifying an Indo-US spectrum. This is the basename of the corresponding fits file.
config.file	name of a configuration file. This can be used to specify a wavelength range to be used with a given target galaxy.
path	optional character string to specify non-standard path to the Indo-US library
lambda.lim	two-component vector giving the wavelength range to be read from the template spectrum. If NULL, the entire spectrum is read.
resolution.target	Instrumental resolution (sigma!) of the spectrum that is to be fitted.
...	Further parameters to be passed to prepare.template.

Details

The Indo-US library is expected to reside in $SLACS_HOME/Indo-US/IRAF. A non-standard path can be given with path.

From a given resolution.target, the routing automatically computes the required width of the smoothing kernel used by prepare.template. The instrumental resolution of the IndoUS spectra is 0.43 Angstroms.

The object name and atmospheric parameters are looked for in keywords OBJNAME, PICKTYPE, TEFF, LOGG and FEH.

Value

An object of class spectrum, resampled to a logarithmic wavelength vector.
