Nl    :  sequential number of a level
Elv   :  energy of the level in MeV
s     :  level spin (unique). Whenever possible unknown spins up to
         Umax were inferred. Unknown and undetermined spins are entered as -1.0
p     :  parity (unique). If the parity of the level was unknown, positive or
         negative was chosen with equal probability. Parities were determined up
         to Umax as in the case of spins. The method of choice is not coded.
             The possible values are: 0 for unknown, +1 for positive and -1 for negative.
T1/2  :  half-life of the level (if known). All known half-lives or level widths
         were converted into seconds. Half-lives of stable nuclei are
         represented as -1.0E+0.
Ng    :  number of gamma rays de-exciting the level.
J     :  flag for spin estimation method (see below the list of possible flags).
unc   :  flag for an uncertain level energy. When impossible to determine, the
         relative energy of the band, the energy of these band heads were set to
         0.0 keV or, if the level order is known, to the preceding level energy
         with a note that an unknown energy X should be added. The notation uses
         X+, Y+, Z+ etc. for different bands.
spins :  original spins from the ENSDF file.
nd    :  number of decay modes of the level (if known). Values from 0 through 10
         are possible; 0 means that the level may decay via gamma-emission,
         and other decay modes are not known.
m     :  decay percentage modifier; informs a user about major uncertainties. 
         The modifiers are copied out of ENSDF with no modification, and can 
         have the following values: =, <, >, ? (unknown, but expected), 
         AP (approximate), GE (greater or equal), LE (less or equal), 
         LT (less then), SY  (value from systematics).
percent: percentage decay of different decay modes. As a general rule  the
         various decay modes add up 100%. There are, however, two exceptions:
         (i) when a small percentage decay is present, the sum may be slightly
         more then 100% due to rounding error, (ii) when beta -decay is
         followed by a heavier particle emission, the percentage of the
         beta-delayed particle emission is given as a portion of the beta-decay
         and the sum can be substantially larger then 100%. Naturally, when the
         modifier is "?" the sum is indefinite.
mode   : short indication of decay modes of a level (see Table below).
shift  : value assigned to the unknown "X", in MeV.
band   : integer assigned to band(s) to which the level is part

1. Ni =0. A unique spin was determined using the spin distribution with sexp. This method is flagged as 'n'.
2. Ni =1. In spite of uncertainties (like (1)+ ), this case was considered to be unique and the flag is 'u'.
3. Ni >1. The spin was chosen from the limited set (eg. (1,3,4)-) using the spin continuous normalized distribution and the flag is 'c'.
4. Above Emax or if unique spins could not be determined due to the lack of experimental spin distribution the flag is left ' ' (blank). For levels with unique experimental spin above Emax the flag is 'u' .

Nf    : sequential number of the final state
Eg    : gamma-ray energy in MeV
Pg    : Probability that a level decays through the given gamma-ray emission. 
        Pg is the ratio of the total electromagnetic decay of the level to the
        intensity of the gamma-ray. If no branching ratio is given in the
        ENSDF file, Pg=0.
Pe    : Probability that a level decays with the given electromagnetic
        transition, i.e., ratio of the total electromagnetic decay of the level
        to the intensity of the given electromagnetic transition. The sum of
        electromagnetic decays is normalized to 1. If no branching ratio is
        given in the ENSDF file, Pe=0.
ICC   : Internal conversion coefficient of a transition.
