This file, errata.txt, contains release notes and errata concerning the
Venus Climate Orbiter RS Bending Angle and Temperature/Pressure Profiles
Data Archive.

During the course of the Venus Climate Orbiter mission the PLANET-C
Project Team may update previously released data products or
documentation; for example, updates may occur due to changes in
calibration data or procedures. Updates will be reported in this file.
Older versions of data and documentation will not be retained in the
archive.

Section A of this file contains an entry for each Venus Climate Orbiter
release (starting with release 1) with general information about the
