A bug are found in 1B21 algorithm for post-boost data (from August 25, 2001 to January 31, 2002), which is using false
information for startBinDist in RAYHEADER for the angle bins 1, 2, 3, 4, 46, 47, 48, and 49.
Since the bug in startBinDist, following items contains offset for those angle bins: binEllipsoid, binDIDHmean, binDIDHtop, and binDIDHbottom.
Difference from true value for each items are (current value -true):
