The full stack of spectra in the SBLA rest frame that are used to calculate the arithmetic mean stacked spectrum (with a 3% top and bottom sigma clipping). Discarded pixels or pixels without wavelength coverage are masked with a value -100. The header is in the format

# [Dimension 1: numbers of SBLAs] [Dimension 2: number of wavelength bins]

The wavelength solution is identical to the stacks and composites cropped to the rest frame wavelength range covered.

		- Stack of spectra for FS0 sample in the SBLA rest frame from 900Ang to 1200Ang. Portions of the spectra with Lyman-alpha forest absorption are included
