    This table contains data from 1972-1974 for the upper gradient bridge of
    Apollo 17 probe 2 in this bundle's 'clean' format. This format flags
    impulsive outliers and missing data using a bitmask, adds a corrected dT
    range to some Lamont-NSSDC data, reorders some inverted time points, and
    places data from Nagihara et al. into the format of the Lamont-NSSDC data.
    See bundle_documentation.md for details. It is basically a corrected and
    marked-up version of PDS3 product
    A17A-L-HFE-3-THERMAL-CONDUCTIVITY-V1.0:a17_HFE_P2_1-201201.
