General description: This file is a FITS binary table identical in form to the spZbest file, but with all the fits ever done to each object. This includes 5 possible galaxy redshifts, 5 possible QSO redshifts, and 1 for each of many types of stars. They are rank-sorted for each object, letting you go through and keep asking "but what's the next best fit?". This is what the IDL procedure plotspec uses when the ZNUM keyword is specified. For example, ZNUM=2 will over-plot the 2nd-best fit eigenspectrum.
Not all of the parameters in the spZbest file are computed for the spZall file. For example, the SDSS filter convolutions are not done.
