    This is a copy of PDS3 product
    A17A-L-HFE-3-THERMAL-CONDUCTIVITY-V1.0:A17_HFE_P2_3-201201. It contains data
    from 1972 to 1974 for the Apollo 17 reference thermometer and the
    thermocouples of Apollo 15 probe 2, restored from tapes provided by
    personnel at Lamont Observatory to the NSSDC. Programs included in
    urn:nasa:pds:a15_17_hfe_concatenated:document_source can operate on it to
    generate products in a15_17_hfe_concatenated:data.
