title Ly alpha forest cloud
c ionized by AGN power law plus cosmic background
background, z=2 ; this includes both black body and AGN parts
double  ; mimic two-siced photoionization
hden -2
stop neutral column density 15
metals -1.5  ;reduce all heavy elements by 1.5 dex
print faint -1
iterate to convergence; must iterate since optically thin
