This cross-correlation of a galaxy spectrum with absorption
lines demonstrates the variety of intermediate graphical and printed
information available when running xcsao. This may help in
understanding how the task computes a redshift.
This cross-correlation of a galaxy spectrum exhibiting both
emission and absorption features shows the variety of graphical
summaries and printed reports in which xcsao reports its results.
These can be used to get a feeling for the quality of the resulting redshift
and to pass on xcsao results for use by other programs.
Example 3. Cross-correlating a Whole Night At Once
To obtain redshifts for a whole night's worth of galaxy spectra using a
list of template spectra:
rv> xcsao @nite1.ls firstname.lastname@example.org
where the file temp.ls contains the names of the image files containing
the template spectra and the file nite1.ls contains the names of the
image files containing the galaxy spectra.
