    1414Understanding the format of this table is crucial to interpolating correctly.  There are a couple of properties that this table must have:
    1515
    16 1.) It must be ordered as log(ne), T, log(X), (9 species cooling fractions), cooling rate. Where ne is the electron density, T is temperature, X is ionization fraction, and the 9 species cooling fractions are the fractions of how much each species contributes to the cooling rate. Note that here log refers to the base 10 logarithm.  The 9 species are ordered as follows: OI, OII, NI, NII, SII, FeII, SIII, MgII, CII.

    18182.) The step sizes of log(ne), T, and log(X) must remain constant.  In other words, each column is evenly spaced.
