gconv

Source - Header - User Guide

Gaussian convolution

dependencies: none


getchelle

Source - Header - User Guide

Reads an iraf-formatted (multispec) echelle spectrum in FITS

dependencies: peval.pro readfits.pro (and its own dependencies: astro library)


getew_xy

Source - Header - User Guide

Automatic determination of the EW of a spectral line by fitting Gaussian and Voigt profiles. The fits are forced to match the continuum at 1.0 and, in the case of a Voigt profile, the center of the line at is fixed to the position determined by the Gaussian fit.

dependencies: mideshift_xy.pro gaussianmia.pro


getphot_xy

Source - Header - User Guide

We derive synthetic photometry for the SDSS system (ugriz) ; from an input spectrum

dependencies: l2nu.pro trapz.pro tfm_unred.pro ( from astro lib)


kmod

Source - Header - User Guide

Extracts and if necessary interpolates (linearly) a kurucz model from his grid. The routine is intended for stars cooler than 10000 K. The grid was ftp'ed from CCP7.

dependencies: rd_kmod.pro


l2nu

dependencies: none


mideshift_xy

Source - Header - User Guide

Measuring the wavelength of the center of a line.

dependencies: none


mmod

dependencies: rd_mmod.pro


peval

Source - Header - User Guide

Iterative evaluation of a Chebyshev or Legendre polynomial

dependencies: none


rd_kmod

Source - Header - User Guide

Extracts a Kurucz model from his theoretical grid. The 'old' grid was ftp'ed from CCP7@Armagh circa 1997. The 'new' (k2odfnew and ak2odfnew) grids were downloaded from Kurucz's web site in 2006.

xc

Source - Header - User Guide

Determination of the maximum of the cross-correlation function of two equal-length vectors by fitting a polynomial or a Gaussian

dependencies: none
