This set of PCKs includes the new traditionally named low-accuracy long-term predict PCK "earth_620120_240827.bpc" and the new traditionally named historical reconstructed PCK "earth_620120_240827.bpc" with coverage starting on 1962 JAN 20, a decade earlier than the previous historical PCK. In addition, this set includes a new PCK "earth_1962_240827_2124_combined.bpc" that for convenience combines high accuracy, historical and low-accuracy predict data in a single kernel. These PCKs and aareadme.txt providing additional details are available in the generic kernels area of the NAIF server: https://naif.jpl.nasa.gov/pub/naif/generic_kernels/pck
