MissionName2DataDir.trn - Converts Mision names into the Isis3 preference name
used to access mission specific data (e.g. space craft clock kernels). This file
replaced Missions.trn as of Isis 3.1.12.

pdsProjectionLineSampToXY_V2.def replaces pdsProjectionLineSampToXY.def for Isis version 3.5.1 and above.  This has the corrected PDS offset data to fix bug m02244 "Pixel (Line/Sample) Projection Offset Issue".
