In the ESO Slice Project, galaxy redshifts were measured with a
cross-correlation technique, as implemented in the external IRAF package
rvsao (task xcsao).
The interested reader may look at the ESP papers to obtain more information and details about data reduction and errors.
Here are the 8 stellar templates (fits files) used in the ESO Slice Project. The file esptemplates.tar.gz includes all of them.
