The "system" files are in order of redshift by index 21-28.  the files are over +/-600 km/s centered 
on the wavelength between 1548 and 1551 so that the system spectrum centers without any plotting fuss

the redshifts are:
zabs.21 = 2.5228000
zabs.22 = 2.5333065
zabs.23 = 2.6949298
zabs.24 = 2.7787169
zabs.25 = 2.8216114
zabs.26 = 3.0060602
zabs.27 = 3.0301598
zabs.28 = 3.0860678

for plotting the systems... the spectral files or "chunks" are:
fort.21
fort.22
fort.23
fort.24
fort.25
fort.26
fort.27
fort.28

J103909-231326.data - the full spectrum, uncleaned
J103909-231326.txt - the portion to plot from Lya to CIV emission, cleaned
J103909-231326.spec.pdf - my rough version of the plot; I marked the locations of the absorbers
