... The technique is based on the iterative subtraction of continuum estimates and eigenvector sky models derived from singular value decompositions of sky spectra and sky spectra residuals. ... The spectra may also be redshifted to a common radial velocity, though this feature isn't used for sky subtraction. svdvec is a Fortran program, called by IRAF as a foreign task, which decomposes an array of spectra, such as that created by svdprep , into eigenvectors using Singular Value Decomposition. ...

. Used with its -u option the sort command removes duplicate lines from a file. For example: sort -u -o mail/labels addresses . This removes all duplicate lines from the file addresses and places the output in the file mail/labels . Duplicate lines do not have to be consecutive for the sort command to identify and remove them.

... 3) Decide which scans were off-Fringe and use them to estimate the background noise. 4) For the on-Fringe scans, estimate the mean square power (per wavenumber bin), subtract the off-Fringe power, and if you have courage, take the square root. ... Some disadvantages of this procedures are: You have to have a good estimate of the off-Fringe noise power; if the nominal signal/noise in a single wavenumber bin is small: (S/N)<1 , then the S/N of the correlated flux after M samples is only (S/N)^2 (M). ...
