Update: 2016-06-20
    Now 626, 636, 646, 666 and 828 line lists have reasonable quantum numbers, here
    (1)line list users can directly download the xxx.296K.1E-36.reduced.list.tgz
    (2)rovibrational energy levels (absolute values in a.u.) can be found in
    (3)the xxx.*compact.tgz files are only for users who may have interests in the compact <--> regular format transformations.

Old Version: June.2014 (Ames-1 PES based)
Download the so2.f90 and .tgz data files (J=0-80 energy levels and transitions) from here:
